To reduce the unfavorable influence of phosphene array irregularity on the form of Chinese character pattern so as to improve recognition accuracy in visual prostheses, two correction methods were put forward. One method was to generate phosphene closest to the target point in regular arrays using weighted nearest neighbor search. The other was to generate phosphene whose center located in the region...
The paper presents a novel and efficient method of regular geometric shape detection from gray scale images. Artificial ant based methods have not been used much in the field of image processing. This paper demonstrates how artificial ants can be used effectively to extract regular geometric shapes from images. We propose here ant regeneration and recombination system (ARRS), an entirely new approach...
The paper proposes two novel and efficient methods of circle detection from gray scale images. As a tool, we have used in one scheme ant colony algorithm. In other scheme, we have used ant regeneration and recombination system (ARRS), an entirely new approach developed by ourselves. In both the schemes presented here, three common steps were followed. Firstly, MATLAB edge detection operator converts...
