I have vertical and horizontal (rectangular) strips in binary image. I want to extract the strips which meet the criteria of specified length and specified width. Area based methods like bwareaopen or bwpropfilt does not help due to no control on second dimention. Any idea thanks

specifically: reactangular regions having at least 4 ones in x and 10 ones in y.

Post your image. Usually when people ask for image processing advice, they give us an image to look at. Doesn't that make sense? About all I can say now is to use imcrop().
