Many of the cancer cases and prenatal cases are to be treated as medical emergency as the chromosomal analysis guide the clinical decision regarding diagnosis, therapy selection, termination of pregnancy etc.
Proceedings of ICACIE 2017, Volume 1
The multidisciplinary approach involving state-of-the-art engineering of microscopes with high resolution, planatic and chromatic aberration free optics, cooled coupled device CCD camera, frame grabber cards, and computer having compatible monitor and processor has changed the face and pace of cytogenetic analysis.
The cluster of 46 chromosomes in normal condition as well as few more or less in various cancer and other disease conditions are expected. In addition, due to the nature of the method, many artifacts, varying degrees of staining intensities etc.
However, the current methods of computer image analysis has proven to be valuable for automation and requirement of skilled human intervention has never been the final goal as it will be unrealistic and technically not sound. Approach We have prepared the algorithm to maximize automation in an error-free manner. A bigger dataset as well as variation in quality of native images has brought about a considerable change in the proposed technique, so as to enhance the accuracy of the output and reducing the computation required.
A cluster of chromosomes along with slide artifacts need to be separated using intelligent algorithm.
The target is to obtain an output image with well-defined vertically aligned chromosomes in the order of length, centromere position and band patterns. The first phase starts with segmentation  of objects for future extraction and analysis. Global threshold value for the image accounts for segmentation of objects from the unwanted background pixels. Thereafter, extraction is performed to administer individual object properties.
Each chromosome is extracted the way it is present in the native image. Hence, for karyotyping proper rotation is necessary. Edge linking techniques like local processing and global processing can be used for detecting edge lines.
However, the former implementation largely depends on pixel similarity measures like magnitude and angle of gradient vector. Thus the space and time complexity increases for processing each and every pixel. A global processing technique such as Hough Transform on the other hand is a way of finding edge points in an image that lie along a straight line, curves and other structures if their parametric equation is known.
It is resistant to noise and can produce multiple instances of a model in a single pass, which proves to be a favorable choice. While vertical rotation takes place, it has to be taken care that the chromosome is properly placed.
This implies that the short arm p-arm for petite should be positioned above the longer arm q-arm for queue. This can be achieved by computing the distance of the centromere from both the ends using Medial Axis Transformation [5, 6, 7]. Following phase deals with merging the individual chromosomes into a karyotype image in the order of decreasing length so as to conform to the ideogram rules.
Signals And System (Full Book) By Ramesh Babu
For band pattern matching, which is the final stage in automatic karyotyping, a density profile signal  has to be computed which produces a 1D vector, the values of which contain the median values of the pixels orthogonal to the skeleton or medial axis. The system takes a native image of any file format as input, and if required converts it to gray scale for processing. Also, minute impurities which may affect processing are removed using morphological operator. After labeling the connected components, their region properties need to be measured so as to accurately define the objects and extract them to individual image files.
These extracted chromosome files may also contain certain images with large unwanted artifacts or conjoined chromosomes.

These may be either deleted or re-segmented using manual intervention, depending on user choice. Next, boundary thresholding is performed which takes into consideration the use of morphological operation, by setting a pixel to zero if its 4-connected neighbors are all ones, thus leaving only boundary pixels. Skeletonization is yet another morphological operation which removes pixels on the boundaries of objects without allowing objects to break apart.
These steps are required in order to facilitate proper chromosome rotation. As mentioned before, Hough Transform computes the edge linkages of the images. The angle of the edge determines the amount of rotation required for vertical chromosome alignment.
As a result of bi-cubic interpolation due to rotation, pixel values are produced which lie outside the original range. Removal of such pixels is obligatory which may otherwise interfere with further image processing techniques. Lengthwise arrangement of chromosomes is also done in the meanwhile, which may ease the process of ordered karyotyping. This facility is provided to the users for pointing out the particular chromosome.
After complete pre-processing of individual chromosomes, it is essential to merge them together in a single karyotype image.
