Embodiment
Referring to the drawings and specific embodiments, the judge's dressing detection method based on video of the present invention is described in detail.Specific embodiment described below is only preferred forms of the present invention, and can not be interpreted as limitation of the present invention.
As shown in Figure 1, judge's dressing detection method based on video of the present invention, comprise the steps: that the personage's head first using DPM algorithm to identify in image in area-of-interest takes on region, obtain the personage's scope in video, then to the method emblem in personage's clothes region, neck emblem, necktie with clothes color utilizes texture, color characteristic detects and judges, finally calculate dressing energy according to the judged result of these independent characteristics and finally judge.
The first step that dressing detects finds people's object area, uses DPM algorithm to carry out training and the detection of personage's head shoulder model in the present invention.First image to be checked is carried out piecemeal by DPM algorithm, then extracts HOG feature to each piece, then calculates the distance of each block to center to obtain the weight of each block, the HOG feature of these Weights undertaken training and detecting by SVM cascade classifier.DPM algorithm as shown in Figure 2.
Gradient orientation histogram (HistogramofOrientedGradient, HOG) feature is a kind of character description method commonly used in computer vision and image processing field, and it extracts characteristic procedure as shown in Figure 3.Just can analyze personage's dressing after finding people's object area.
Dressing needs the independent characteristic detected to be method emblem, neck emblem, necktie and clothes color in detecting.The method that wherein method emblem, neck emblem, necktie adopt extraction HOG feature to carry out the training of SVM cascade model obtains corresponding prior model, and the position that then may exist at these independent characteristics is detected, and finds doubtful feature.Corresponding territory, left regio pectoris, method emblem, the shoulder central area that neck emblem and necktie correspondence vary in size.While use SVM cascade classifier carries out training, also need to use neural network to carry out the training of independent characteristic.After finding doubtful feature, re-use neural network and confirm, obtain method emblem, whether neck emblem, necktie exist.
Another independent characteristic that dressing detects is clothes color, the detection method of clothes color is, according to priori, obtain the hsv color spatial dimension of the clothes color of closing rule, then the people's object area obtained by DPM carries out cluster according to hsv color space, thus find maximum conjunction rule color region, judge whether this region meets personage and wear scope clothes to determine whether clothes color closes rule.
After the detection completing each independent characteristic, according to setting different energy of wearing each clothing type of weight calculation of each independent characteristic corresponding to type clothes, possess independent characteristic then energy increase, otherwise energy reduces.Regular judge's robe need possess neck emblem, method emblem, color characteristic, and trial clothes and trial in summer clothes need possess different method emblems and different colours feature.When energy continues to increase and exceedes certain threshold value, think that rule are closed in current people's dressing, when energy continues reduce and exceed certain threshold value, then think that current people's dressing in violation of rules and regulations, when energy is between two threshold values and when shaking, thinking there is no conclusion, according to detection Stringency, being classified as different conjunction rule and violation results by there is no conclusion.
