Constructing a Vec File Based on Positive Narrow Helix Samples
After creating our description file of positive and negative samples, the next step towards building our classifiers includes packing the positive samples into a vec file.
Building a vector file is done via the opencv_createsamples utility. Opencv_createsamples allows us to generate a large number of samples from a small number of input images by applying distortions and transformations to positive samples.
We wrote shell scripts to automate using a few of the opencv command line tools. The shell script for createsamples is below.
