Pedestrian clothing color identification method based on digital image processing

Abstract

The invention discloses a pedestrian clothing color identification method based on digital image processing. The method comprises the steps that (1) a pedestrian detection method which combines an HOG feature description operator and a SVM classifier is used to acquire a pedestrian image; (2) a Sobel operator is used to detect the edge contour shape of a pedestrian to acquire an image to be searched; (3) a pedestrian contour shape template is produced and matches a corresponding region in the image to be searched to acquire upper and lower body images of the pedestrian; (4) a seed filling method is used to carry out communication region labeling on clothing colors of upper and lower body regions of the pedestrian; (5) color feature extraction is carried out on a color communication region; and (6) the SVM classifier is used to carry out color classification discrimination to acquire the clothing color of the pedestrian, and a final result is output. According to the invention, the identification accuracy of the clothing color of the pedestrian is improved; standardized dress in a dangerous region is ensured; and safety risks are eliminated.

Description

technical field [0001] The invention relates to a color recognition method, which belongs to the technical field of image processing, in particular to a method for recognizing the color of pedestrian clothing based on digital image processing. Background technique [0002] Safety is an eternal theme in special fields such as electric power and oil and gas fields. In recent years, various safety accidents in oil and gas fields and electric power industries have occurred from time to time. How to strengthen the safety production capacity and improve the management level of oil and gas fields and electric power enterprises has become the primary problem that relevant personnel must face. [0003] One of the potential safety hazards in oil and gas fields, electric power and other fields is that workers do not strictly enforce the dress code in designated work areas, and do not wear special safety clothing as required. At the same time, as the country pays more and more attentio...
