Is there such a way to create an image like the one below in MATLAB? I am interested in numbering some of the pixels in the manner like below. I have to change the parameters often and as such would like to automate the process (the general orange shape would be the same though).
Even a hint would be appreciated.

My first thought is to have a go at w/ text in an axes object. The grid is easy enough just with '[x|y]grid','on' and set a solid linestyle. The background would have to be patch I think...there I have little hands on experience, sorry...
The basics of the above would be an array of nan(10,11) with the values stored in the proper x,y coordinates.

Perhaps you could make that an image with those values. Then use im2html: http://www.mathworks.com/matlabcentral/fileexchange/32273-im2html-m written by Steve Eddins of the Mathworks Image Processing team. I haven't tried it with a gray level image but I'd guess it would create a grid with the gray levels in the boxes instead of RGB values if you passed it a gray level image. It would be easy to modify if it didn't. However the shading of the box is the same as the gray level so you'd have to make a slight adaptation to make the box a constant orange color. And make another adaptation that if the value is zero to not display any text in the box.

thanks. I ended up writing my own code for a simpler version of the problem. The comments were indeed helpful and inspired the method.
