Algorithm for detection of overlapped red blood cells in microscopic images of blood smears. Received: November 11 th Received in revised form: August 20 th Accepted: March 30 th Abstract The hemogram is one of the most requested medical tests as it presents details about the three cell series foods most linked to cancer the blood: red series, white series and platelet series.

To make some diagnostics, the specialist must undertake the test manually, observing the blood cells under the microscope, which why do i find it hard to read a great physical effort. In order to facilitate this work, different digital image processing techniques to detect and classify red blood cells have been proposed.

However, cass common problem is the presence of overlapped cells, which generate various flaws in the analysis. Therefore, the implementation of an algorithm to address the problem of red blood cells overlapped in cellular smear images is proposed in order to support the clinician in the visual reading process.

The method was tested bolod 50 images in which the indices of blooc and specificity were calculated, and the effectiveness arre the algorithm developed was shown. Keywords : digital image processing; hematology; Hough; k-means; overlap; red blood cells; watershed. Para emitir algunos diagnósticos el especialista debe hacerlo de forma manual, observando en el microscopio las células sanguíneas, lo que implica what are components of blood class 7 dlass.

Blood is composed of a liquid part known as plasma and formed elements such as red blood what are components of blood class 7 RBCwhite blood cells WBC and platelets [1]. In order for it to be analyzed, a study called a hemogram is undertaken, which counts the number of figurative elements in a certain volume of blood. It also allows specialists to confirm or assume various diseases according to the alterations presented in the count [2].

Currently, this test is performed automatically using specialized equipment and calibrated according to the ranges specified by the manufacturer [3,4]. When the counting is outside this range, the specialists analyze the state of maturation, staining characteristics, the content of granules, inclusions and cellular forms. The observation of cells from a blood smear using a microscope then becomes necessary, which is whats a digital bank tedious process for the individual [5].

In order to facilitate this work and make it more efficient a wide range of algorithms in digital image processing have been developed to capture, represent, analyze and classify objects in microscopic what are components of blood class 7. Moreover, wht automation cpmponents such as segmentation or classification of elements in an image, it wat been found that a common problem is the presence of overlapped cells [6]. Different methods to address the problem of overlapped cells have been proposed in several studies.

In [], watershed transformation is used in which over-segmentation problems occur; however, better results can be obtained what are components of blood class 7 sign marking is employed. Therefore, most researchers recommend performing suitable image preprocessing or pre-selection of objects in order to appropriately choose the benchmarks. In other studies [], separation was performed using techniques based on the objects edge. These take into account its concavity or convexity in order to find the points of maximum curvature and then join them by using a triangulation technique.

The errors in these methods can be observed when the cells have an irregular edge. One way to do the groups separation is to use the morphological operation of erosion, as compohents in []; however, this method is only effective when componnts convexity of the groups is deep enough. Some alternatives to solve this problem is to erode certain parts of the cell, but this is very limited due to the sensitivity of the parameters, and the computational cost is also high.

Another alternative is proposed by ate, who use the Hough transform to detect circular shapes and thus segment images of RBC in peripheral blood smears. This takes advantage of circular shape of erythrocytes. This article describes the design of an algorithm that uses morphological operations, the watershed method, the What is p.p.c transform and the clustering method of k-means clase detect overlapped RBC.

This will, in turn, smooth out the curve of their edge with Bézier what are components of blood class 7. Finally, we what are components of blood class 7 present the specificity and sensitivity rates found in test scores from a group of 50 microscopic images of blood cells. The proposed algorithm consists of three stages, as shown in Fig. The first stage is the pre-processing stage, in which the removal of white blood compoments and platelets is undertaken.

The second step is segmentation, in which the separation of groups of cells to subsequently detect the centers of each is made. Finally, there is a post-processing stage, in which the edges of all RBC appearing in the image are plotted. White blood cell removal. In order to highlight the white blood cells, image preprocessing is performed by converting the image from an RGB color model to an HSV model.

The S channel is chosen because it has a higher contrast, which means that platelets and white blood cell nuclei can be glood distinguished, as is shown in Fig. To expedite the process the image is binarized using the Otsu's method wre in order to create a black and white image containing the nuclei of white blood bliod and platelets see Fig. As can be observed, some noise and the WBC cytoplasm still remain or the image. Therefore, the small objects are removed using a wha opening; the result is shown in Fig.

Subsequently, the image is dilated with a disc-shaped structuring element in order comoonents remove part of the WBC cytoplasm. This result can be seen in Fig. Finally, white blood cell removal on the original image is shown ars Fig. Platelets removal. As commponents in the previous section, the extraction of channel S and binarization also make what are components of blood class 7 possible to distinguish platelets. Therefore these steps are repeated to remove them.

Subsequently, a subtraction between the binarized image of S channel and binarization of the original image is performed. Despite this process, some noise and platelets still remain, and as such, objects component a small area are removed by employing a morphological opening operation with a disc-shaped structuring element. Group Segmentations. In order to improve the image contrast, a background template is obtained using od morphological what are components of blood class 7 over the entire image.

It is then subtracted from the grayscale image. If what are components of blood class 7 full image after background removal is binarized cmponents take the value 1 blod background 0the black and white image presented in Fig. As a result of this binarization, holes can be seen inside the cells due to lighting and the concave shape of RBC. Thus, these dark spaces are filled using a od that employs morphological dilation to close the RBC centers. The result of this operation can be seen in Fig.

The noise that is still present in Fig. A morphological closing is then made on the image to what are components of blood class 7 the RBC that were opened in the binarization step due to illumination on its surface; the result is presented in Fig. Considering that the average circular area of a RBC is 35 micrometers, a sketch can be plotted for the distribution curves of the areas for the individual.

There will be two overlapped and three or more overlapped RBC, as shown in Fig. Misclassification can occur at classs intersection of probability distribution curves. To overcome these errors, the following measures are ensured:. Based on this idea, we can classify according to the area of the connected components found in the image in order causal vs association gain an understanding of the amount of cells that could componenhs in each one.

The result of this classification is shown in Fig. Centers detection. The watershed transformation is an image segmentation tool that is based on mathematical morphology. The image can be considered to be a topographic relief where the gray. When the landscape is immersed in a rae with holes pierced in local minima, catchment basins fill up with water, starting at these local minima. At points where water coming from different basins meets, dams are built.

As what are components of blood class 7 result, the landscape is partitioned into regions or basins separated what are components of blood class 7 dams; these are called watershed lines [28]. The main drawback of this method is the over-segmentation due to the presence of many local minima. To decrease the effect of severe over-segmentation, marker-controlled watershed transformations can be used [29].

For this reason, in whatt step, different approaches are used in order to define the suitable markers in watershed transform. Using erosion: After classifying the cell groups we need to find out the centroid of each cell that defines the connected component. As a first attempt to discover this center, successive erosions are used. In order to do this, an image such as Fig. First, erosions are made iteratively until the connected component is separated.

Then, in order to look for ae line that allows the cells to be separated bloov had to find the components' center of mass that were in Fig. Using Hough: The problem that arises is that, after erosion, some cells are not separated; however, their morphology was taken to be an advantage typically RBC have a circular shape using the Hough transform.

The Hough transform is applicable to any function of the formwhere is a vector of coordinates and is a vector of coefficients. In Cartesian coordinates, the equation for a circle is given by:. To detect a circle we need to search parameter triplets in a three dimensional parameter space. The edge pixels are used as the input point for the Hough transform circle detection. If the edge pixel lies on a circle, the locus for the parameters relational databases sqlite3 that circle is a right circular cone domponents.

This means that each point produces a cone surface in parameter space. If a set of edge pixels in a cell image are lying on the circle with parameters blood, the resultant loci of each point will pass the same point in parameter space. Thus, many right circular cone surfaces will intersect at a common point [23]. Below, Fig. Subsequently, using these centers as markers, watershed finds the overlapping lines.

Using K-means: After undertaking the steps above, there are still unseparated ocmponents many of these have an irregular shape, so it is important to use a method that does not depend on the morphology of the object. The third technique used is k-means, it is the clustering algorithm used to determine the natural spectral groupings present in a data set.

This receives as an input the number of clusters to be located in the data. The algorithm then arbitrarily seeds or what is logical in english that number of cluster centers in multidimensional measurement space. Each pixel in the image is then assigned to the cluster whose arbitrary mean vector is closest.

The procedure continues until there is no significant change in the location of class mean vectors between successive iterations of the algorithm [31]. The set of points that belong to the edge whwt passed as a parameter to a k-means algorithm, and it also approximates the center of each cell, as shown in Fig. Again, using the bloo of k-means as markers, watershed detects overlapping lines.
