hello, sorry if this is a dumb question but for making cascades you must use positive images. i plan to use our own images, of an animal for an animal identification software, and according to the cascade tutorial (middle of the page), i must make a file that lists where the positive object is in the image. it says to label the x,y coordinates as well as the height and width of a bounding rectangle. i dont understand how i would get all those parameters manually and the tutorial doesn't seem to mention it either.

also, any advice on how i would get all those parameters as quickly as possible? thank you in advance.

By dowloading the annotation tool I submitted as a PR! This is the most time consuming step for efficiently training classifiers, but it is worth the hassle in the end!

When I needed positive samples I drew a rectangle on my video feed and then just hit the space bar when my target was 'centered', saving the interior of the rectangle as a positive image sample. If you can capture your positives with video, then this is a decent solution, otherwise a tailored tool like Steven suggests is the way to go.

thank you Steven and Der, i will be using the annotation tool more than likely.
