Optimization of Visual Information Presentation for Visual Prosthesis

Algorithm 1

The main steps of the image segmentation algorithm.
Count and rank the pixel values in the saliency maps.
The higher threshold is set as the pixel value in the 70% place of the ranked
pixels. The lower threshold is set at the 40% of the higher threshold value.
If , the pixels are set as the strong target. If , the pixels are set as
the weak target.
When there is a connected region between the weak target pixel and the strong
target pixel, the weak target pixel is added to the strong target set. Until all the weak
targets have been traversed, the strong target region contains the final segmentation
results.
