how can i declare variables in for loop

28 次查看(过去 30 天)
hi everyone I want to write a function to deal with image which has been divided to N regions with regionprops function : imageregion = [1 2 3 4 ... n] , for every region i in that image I want to declare variables using for loop like this
for i=1:N
vector1=ismember(labelimage,1)>0;
vector2=ismember(labelimage,2)>0;
.
.
vectorn=ismember(labelimage,n)>0;
end
I try to apply that code but i failed . could any help me thank you

what i want exactly is to delete some regions which has particular properties from that image and leave the others . the regions number is not consonant,its differs from image to image. thank you for your help

instead of that , does MATLAB has a function to remove undesired regions ( small regions or the area we wish) from a binary image to another one ?

Short summary: Don't do this! Use an array instead of a pile of variables with an index hidden in the name.

There is no reason to do that. You are extracting individual blobs one at a time into "n" binary images with just one blob. Then you're doing that same thing "N" times. There is no reason to do it more than once, and there is not even any reason to do it once. You don't need n images, and don't need to generate n images N times. Why do you think you need to do this? What do you think it will allow you to achieve?

Then use a cell array. See the FAQ http://matlab.wikia.com/wiki/FAQ#What_is_a_cell_array.3F and see my Image Segmentation Tutorial in my File Exchange http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862. In there I show you how to filter blobs based on certain feature values.
