DEVICE WITH DATASTREAM PIPELINE ARCHITECTURE FOR RECOGNIZING AND LOCATING OBJECTS IN AN IMAGE BY DETECTION WINDOW SCANNING

摘要

A device for recognizing and locating objects in an image by scanning detection windows comprises a data stream architecture designed in pipeline form for concurrent hardware tasks and includes means for generating a descriptor for each detection window, a histogram determination unit determining a histogram of orientation gradients for each descriptor, and N processing units in parallel, capable of analyzing the histograms as a function of parameters associated with the descriptors to provide a partial score representing the probability that the descriptor concerned contains at least part of the object to be recognized, the sum of the partial scores of each detection window providing a global score representing the probability that the detection window contains the object to be recognized.
