Creating our description file of positive narrow helix samples

After collecting positive training images of narrow helixes we cropped our sample images of ears to just the portion that contained the helix. This cropping was done using an open source object marker tool written in python.

The object marker allows us to specify the region of interest by drawing a bounded rectangle object in each positive image then produces a text file description of the coordinates corresponding to the location of the helixes.

This data will be used to construct our positive vector file to eventually train our classifier.
