Abstract

The embodiment of the invention discloses a method and system thereof for television image enhancing based on skin segmenting. The method comprises the following steps of receiving an input image; classifying colors of the input image, so as to obtain a color classifying result; extracting textural features of the input image; segmenting the textural features, and outputting a segmenting result; according to the segmenting result, establishing a location model; linearly sampling the location model, until the resolution of the input image is obtained; and combining the color classifying result and the resolution of the input image to generate a skin segmenting result. According to the embodiment of the invention, by adopting one trainable color feature and the multi-size textural features, the false reporting rate of detection is reduced, the processing speed is increased, the loss is reduced, and the effect of enhancing the television image is realized.

Description

technical field [0001] The invention relates to the technical field of television images, in particular to a method and system for enhancing television images based on skin segmentation. Background technique [0002] With flat panel displays in HDTV systems, signal impairments are unavoidable. Image restoration and image enhancement are standard features in current digital televisions. As a solution, content-based image processing techniques can be used to obtain higher levels of image quality improvement, thereby surpassing traditional methods of image enhancement for television. The image restoration function restores lost or damaged image information through deinterlacing and noise reduction. Image enhancements, such as improving sharpness, contrast and color, are designed to create a more pleasing image. If the image is analyzed, the image content is detected and segmented, and the enhancement algorithm is processed for specific content, the current TV image enhanceme...
