摘要： A system and method for enhancing the detail edges and transitions in an input video signal. This enhancement may be accomplished by enhancing small detail edges before up-scaling and enhancing large amplitude transitions after up-scaling. For example, detail edge enhancement (detail EE) may be used to enhance the fine details of an input video signal. An edge map may be used to prevent enhancing the large edges and accompanying mosquito noise with the detail enhancement. Noise may additionally be removed from the signal. After the fine details are enhanced, the signal may be up-scaled. Luminance transition improvement (LTI) or chrominance transition improvement (CTI) may be used to enhance the large transitions of the input video signal post scaler.
摘要翻译：一种用于增强输入视频信号中的细节边缘和转换的系统和方法。该增强可以通过在升级之前增强小的细节边缘并且在升级之后增强大的幅度转换来实现。例如，细节边缘增强（细节EE）可以用于增强输入视频信号的细节。可以使用边缘图来防止在细节增强时增强大边缘和伴随的蚊子噪声。噪声可以另外从信号中去除。精细细节增强后，信号可能会升格。可以使用亮度转换改善（LTI）或色度转变改进（CTI）来增强输入视频信号后缩放器的大转换。

摘要： Devices, systems, apparatuses, methods, and other embodiments associated with bit resolution enhancement are described. In one embodiment, an apparatus includes logic configured to produce a high-resolution pixel from a low-resolution pixel. The apparatus includes logic configured to classify the high-resolution pixel as being in a smooth region of an image based on at least one of a gradient value and a variance value associated with the low-resolution pixel. The apparatus includes logic configured to selectively re-classify the high-resolution pixel as not being in the smooth region of the image based on a set of neighboring high-resolution pixels associated with high-resolution pixel. The apparatus includes logic configured to selectively filter the high-resolution pixel based on whether the high-resolution pixel remains classified as being in the smooth region of the image.
