New performance measures in object detection

The article is devoted to new approaches in accuracy evaluation of information retrieval systems (with tests made for motion detection algorithms). First part of article is devoted to studying of how good is tested motion detection algorithm. New elements are added to ROC for computing new measures. These elements are based on Equal Error Rate criterion. Second part of article is devoted to visualization of progress for multiple-step motion detection algorithms. Any algorithm of this type is a set of blocks and it is important to know which gain in accuracy was achieved in N^th step. Elements of design of multiple-step motion detection algorithms are discussed. Another discussed type of visualization is dedicated to boosting (combination of two and more algorithms).
