Claim 0:
1. A computer-based method of object detection, the method comprising:
receiving an annotated image dataset comprising rectangles which surround objects to be detected and labels which specify a class to which an object belongs;
calculating areas of high and low probability of rectangle distribution for each class of objects within images of the dataset;
applying a correction factor to confidence values of object prediction results, obtained during validation of a trained object detection (OD) model, depending on a class label and a rectangle location of an object prediction result;
calculating an accuracy of the trained OD model;
increasing the correction factor and re-calculating the accuracy of the trained OD model with every increase; and
selecting an optimal correction factor which yields a highest accuracy.
