Embodiment Construction

[0038] Such as Figure 1 to Figure 4 As shown, the present invention discloses a method for fast detection and recognition of home appliance gestures based on partial image enhancement, which includes the following steps:

[0039] Step 1. Offline detection and recognition model training

[0040] The offline refers to a model learned in advance before the specific home appliance gesture recognition runs; the model is a knowledge base learned in advance.

[0041] Step 1.1, Human Hand Raising Posture Model Training

[0042] By collecting pictures and videos of various lighting and distances of people's hand gestures, such as figure 2 As shown, the circumscribed rectangular frame of the upper body and the arm is manually calibrated as the positive sample, and then a large number of pictures of other scenes and poses are selected as the negative sample, and the positive and negative samples are sent to the deep convolutional neural network detector for learning, and it is possib...

Abstract

The invention relates to a local image enhancement-based home appliance gesture quick detection identification method. The method comprises the steps of extracting a motion region in an image sequenceby adopting a mobile detection method; in the motion region, detecting a hand raising posture of a person by adopting a detection algorithm, and locating a hand region; performing local enhancement on the hand region; and identifying specific gestures by utilizing an identification algorithm. According to the home appliance gesture quick detection identification method, the hand region is subjected to image enhancement, so that the region is clearer, remote home appliance gesture control of multiple complex light rays can be adapted, the problems of false identification and missing identification caused by unclear gestures are effectively avoided, and the user experience is improved.

Description

technical field [0001] The invention relates to the field of gesture recognition, in particular to a method for fast detection and recognition of home appliance gestures based on partial image enhancement. Background technique [0002] Gesture control is a very convenient method in home appliance control. Gesture control has the characteristics of non-contact, fast and convenient. [0003] At present, gesture recognition is generally realized based on images, which has the advantages of long recognition distance and low cost. However, this recognition is more dependent on image quality and needs to deal with various complex lighting environments. Simply adjusting the global ISP cannot make the image of some areas of the hand clear, and unclear gestures are likely to cause misrecognition and missed recognition. This leads to false triggering and missing responses of instructions, resulting in poor user experience. Contents of the invention [0004] The purpose of the pres...
