Hi,

I am working with visual studio 2010 for image processing main.

My pictures are tables with gray level color(black-white-gray) I want to make it bi-linear, I mean I want to create an threshold box and make them black and white.

But before this I have to make this image clear and Improve the image edge sharp.

After that I want to cluster the same and near homes.

I need some good advise to do this work.

i have a grey value image.its contain table that is not clear(assume that its look like crossword puzzle with different color in each segment and i want to make this image blake and white)
i want to apply edge detection on it first to find edge and make edge enhancement .Then i want to binarize it with selective threshold value and at the end of the work i want to clustering the same color

You have a grey value image.
You want to apply edge detection on it.
Then you want to binarize it.

Is that what you mean?

A simple binarize operation would be possible to implement on your own. Edge detection is somewhat more complicated. But there are image processing libraries out there that contain tested code. And they are most likely speed-optimized to some degree. Have a look at OpenCV for C#[^]

Or read the article series by Christian Graus[^] dedicated to image processing.
