Abstract

The invention discloses a tooth identification method and system based on YUV color space, and a shooting terminal. The method is characterized by collecting tooth sample data, converting the tooth sample data into the YUV color space and carrying out tooth modeling to obtain a tooth model graph; carrying out face identification and tooth primary positioning on an image to be processed to obtain a mouth area comprising teeth; carrying out YUV color space conversion on the mouth area to obtain a converted imaged; and finally, obtaining tooth probability value corresponding to each pixel point of the converted imaged by searching the tooth model graph, and thus a tooth probability graph is obtained. Therefore, quick and automatic tooth identification is realized.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a tooth recognition method based on a YUV color space and a system and a shooting terminal for applying the method. Background technique [0002] With the advancement of technology, more and more devices equipped with high-definition or miniature cameras or image acquisition devices appear, such as digital cameras, mobile phones, tablet computers, and even notebooks. Whether it is the pixel, aperture of the camera equipment, or the light of the shooting environment, the smoothness or even the I / O performance of the equipment, etc. will affect the imaging quality, and the result is that there is a gap between the imaging and the real picture in the real world. This gap may go against the wishes of the device user, or fail to meet the aesthetic requirements of the user. The various image post-processing software derived from this can process the color of the image, so tha...
