This is based on Harris Corner detection i will handle the implementation but needed some help showing these intermediate steps:

this is supposed to only use Java

1.computing products of derivatives and visualizing the three products using the three channels of a color image;

2. calculating corner response under user specified sensitivity parameter and displaying the results as a

grayscale image;

3. showing the results of thresholding; and

4. performing non-max suppression and displaying the detected corner pixels.
