Abstract

The invention discloses an image gesture identification method and device, an image color white balance adjustment method and device, an exposure adjustment method and device. The image gesture identification method comprises the steps of detecting a face area in an image; determining a white balance parameter for adjusting a color of the face area into a skin color; carrying out white balance adjustment of the color on the image according to the determined white balance parameter; and identifying a gesture in the image after the white balance adjustment of the color. Through application of the methods and the devices, the problem that the image color distortion is serious is solved without manually carrying out the color correction, so the accuracy of identifying the gesture in the imageis improved.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method and device for gesture recognition, color and white balance adjustment, and exposure adjustment in an image. Background technique [0002] Gesture recognition technology has been widely used in various home appliances, such as smart TVs, electronic picture frames, etc. One of the more commonly used and relatively reliable techniques is to use the method of adaboost detector or deep learning training detector to train a detector that can traverse and locate the human hand area on a frame of image and label it. This method usually requires the use of LBP, HAAR, and color features (for the adaboost method); while the deep learning method does not specify features, but the color distribution of the target itself is a significant feature. [0003] Gesture detectors that do not use color features can also recognize most gestures, but they will make mistakes on some o...
