Hello,
I have an image.I need to find the row and col for a non zero pixels. I need to find the following pairs of rows and columns :
i) Minimum col and the corresponding row whose pixel values are non-zero.
ii)Minimum row and the corresponding col whose pixel values are non-zero.
iii)Maximum col and the corresponding row whose pixel values are non-zero.
iv) Maximum row and the corresponding col whose pixel values are non zeros.
I am attaching the image with the places marked with red line where i need find the rows and columns.
Please let me know how to find this using find() and any() functions in MATLAB
Looking forward to hear from you at the earliest.
Thanks
Pankaja
