how to save the pixel location in files my aim is to ground truth thousands of images with the pixel location (position) just Y coordinate , so after reading the image and getting the pixel info (impixelregion) I want to save the position that I click on in a file with the same name as the image name I know that I can save this position by right click and copy it in a file but this is really time consuming with lots of images

thanks

Use save() to save in a proprietary binary MATLAB format file. Or you can use fprintf() to save them to a text file.

yes , I did that , but my problem is how to get the location of the pixel and save it in just one click , by only one click I want this location to be saved in a file //////////// code////////// I = imread(image) impixelinfo p = (a variable to handle the position of pixel that I click on) f = fopen('file','w'); fprint (f, p); fclose(d);

thanks
