INTERNATIONAL JOURNAL OF PURE AND APPLIED RESEARCH IN ENGINEERING AND TECHNOLOGY A PATH FOR HORIZING YOUR INNOVATIVE WORK INTENSITY BASED NUCLEI SEGMENTATION OF CANCER CELL

Abstract Automated detection and segmentation of cell nuclei is an essential step in breast cancer cell for improved accuracy, speed, level of automation and adaptability to new application. The goal of this paper is to develop efficient and accurate algorithms for detecting and segmenting cell nuclei in 2-D pathological images. In this paper we will implement the utility of our nuclear segmentation algorithm in accurate extraction of nuclear features for automated grading of (a) breast cancer, and (b) distinguishing between cancerous and benign breast histology specimens. In order to address the issue the scheme integrates image information across three different scales: (1) low level information based on pixel values, (2) highlevel information based on relationships between pixels for object detection, and (3)Intensity-specific information based on relationships between pathological sample. Low-level information is utilized to generate likelihood that each pixel belongs to an object of interest. Highlevel information is extracted by a level-set algorithm, where a contour is evolved in the likelihood scenes generated by the Low-level information to identify object boundaries, and to identify nuclei from the low-level likelihood scenes. Structural limitations are imposed via intensity based specific knowledge in order to verify whether the detected objects do indeed belong to structures of interest. The efficiency of our segmentation algorithm is evaluated by comparing breast cancer grading and automated benign cancer detection of nuclei with corresponding accuracies obtained via manual detection and segmentation of nuclei
