This paper presents an algorithm to capture outline of bitmap characters. In order to obtain outline, a cubic function with one shape parameter is used. Genetic algorithm is applied to find the value of shape parameter. The procedure of capturing outline consists of the steps: boundary detection, detection of corner points, break points and fitting the curve.
Spot segmentation-the second essential stage of cDNA microarray image analysis-constitutes a challenging process. At present, several up-to-date spot-segmentation techniques or software programs-proposed in the literature-are often characterized as “automatic.” On the contrary, they are in effect not fully automatic since they require human intervention in order to specify mandatory input parameters...
In this paper, an algorithm is described which detects and localizes shapes in grayscale images. Deformable templates are often employed to model the geometry of the object to be found in an image. There are several methods to find the optimal placement and deformation of the template onto the image. A genetic algorithm is designed which takes the object template and processed grayscale image and...
