Abstract
A dilation image is generated from an original digital image utilizing a processing image (b) and a target image (T), where each pixel in the target image is processed in parallel. The process entails, for each target pixel, i) determining coordinate values for the target pixel, ii) determining a surrounding pixel area for the target pixel, iii) and processing each pixel in the surrounding pixel area to determine whether or not to updated the value of the target pixel. In processing each surrounding pixel, a determination is made whether the pixel has a value of 1. If not, then the next surrounding pixel is processed. If so, then a determination is made which pixel element of the structuring element overlays the target pixel, and whether that pixel has a value of 1. If so, then the value of the target pixel is updated. If not, then the next pixel in the surrounding pixel area is processed. Once the target pixel has been updated one time, the processing of the remaining surrounding pixels is terminates. If processing of all surrounding pixels results in no update to the target pixel, then the target pixel is not updated. After all target pixels have been processed, the resultant image is output as the dilation image.
