A New Plant Cell Image Segmentation Algorithm
نویسندگان
چکیده
A new plant cell image segmentation algorithm is presented in this paper. It is based on the morphological analysis of the cell shapes and on gradient information. The diiculty of the segmentation of plant cells lies in the complex shapes of the cells and their overlapping, often present due to recent cellular division. The algorithm presented tries to imitate the human procedure for segmenting overlapping and touching particles. It analyzes concavities in the shape of a group of cells as well as the existence of a coherent surface for the segmentation. The algorithm can be divided in two main parts, rstly a simple method for nding dominant concave points in shapes is introduced and secondly several parameters between concave points are calculated as a criterion for se-gmentation. It has been also shown that the algorithm produces good results when the output is applied as a marker for the morphological watershed algorithm. Results will be presented in real images of a cell suspension culture to show the validity of the chosen approach.

متن کاملImage Segmentation using Improved Imperialist Competitive Algorithm and a Simple Post-processing
Image segmentation is a fundamental step in many of image processing applications. In most cases the image’s pixels are clustered only based on the pixels’ intensity or color information and neither spatial nor neighborhood information of pixels is used in the clustering process. Considering the importance of including spatial information of pixels which improves the quality of image segmentati...
