Abstract

The present invention is to provide a method of detecting an object and multi-class boosting classification algorithm used thereby, comprising the following steps: in the given image data, calculating the integral image so as to accelerate the extraction of object's characteristics; then performing a scanning process at a plurality of blocks on the image data with different sizes and locations; and detecting various objects by the use of multi-class boosting classification algorithm (MBH-Boost) during the scanning. In the detection architecture of the present invention, only a single boosted cascade is needed to determine the position and status the object may appear in the image; thus, the invention may detect a variety of objects at the same time or detect the polymorphism of the objects of a specific category with higher precision and execution speed as well as the detection robustness. At the same time, the detection of the polymorphism may solve the problems resulted from the various characteristics of the object under different circumstances, largely improving the robustness of the system.
