摘要： Systems and methods may provide for conducting a real-time perceptual quality analysis of a video, wherein the perceptual quality analysis includes at least one of a noise measurement, a contrast measurement and a sharpness measurement. One or more strength parameters of one or more post-processing modules in a video processing pipe may be set based on the perceptual quality analysis resulting in overall video processing that adapts to the changing perceptual quality of the input. In one example, the strength parameters include at least one of a contrast parameter and a de-noising parameter. The invention results in visually enhanced video at the output of the post-processing module.

摘要： A sharpness metric represents a control variable of manual (47) or automated (41) sharpness control systems for image and video acquisition, storage and reproduction systems. In manual systems usually one controllable parameter is adjusted seeking to maximize sharpness, within pre-established limits to avoid image distortion. A method for measuring sharpness (10) in an image or picture that may have been enhanced asymmetrically uses statistics from a Discrete Cosine Transformation on predetermined blocks of the image and compensates for asymmetry using information on a number of edge pixels (14) and an energy content of one or more vertical edges and one or more horizontal edges in each block (15). One embodiment for so doing determines a kurtosisbased sharpness metric of the image (12) and then compensates the kurtosis-based sharpness metric to account for differences in sharpness enhancement in a horizontal direction and a vertical direction (13).

摘要： Techniques are described that can be used to identify blocking artifacts in both vertical and horizontal directions. For blocking artifacts in a vertical direction, a horizontal gradient is determined for a pixel. Gradient smoothing is performed for pixels in the row of the pixel. A ratio of the horizontal gradient over the gradient smoothing is determined. Any pixel with a ratio above a threshold and in a segment with a length that exceeds a threshold length as potentially having block artifacts. Each column with pixels that potentially have block artifacts is inspected to determine whether a number of block artifacts in the column are a local maximum and whether there is a sufficient number of blocking artifacts in the column. Columns that satisfy both conditions are considered to include blocking artifacts. To determine blocking artifacts in the horizontal direction, a similar technique is used as described with regard to vertical direction except row and columns are reversed.
摘要翻译：描述的技术可用于识别垂直和水平方向上的块状伪影。为了在垂直方向上阻挡伪像，针对像素确定水平梯度。对像素的行中的像素执行梯度平滑。确定梯度平滑的水平梯度的比率。比率高于阈值且长度超过阈值长度的区段中的任何像素可能具有块伪像。检查具有可能具有块伪像的像素的每列以确定列中的块伪像是否是局部最大值以及列中是否存在足够数量的块伪像。满足这两个条件的列被认为包括阻塞伪像。为了确定水平方向上的块效应，除了反转行和列之外，使用与垂直方向相关的类似技术。

摘要： One implementation of a method for edge directed video de-interlacing in accordance with the disclosed invention includes obtaining at least a portion of a field of input video data including at least portions of four consecutive rows of field pixels including first, second, third, and fourth rows of field pixels. The method further includes selecting an orientation over which to de-interlace the input video data based, at least in part, on a measure of the deviation in pixel values among the four consecutive rows of field pixels and a fifth row of pixels located between the second and third rows of field pixels, the fifth row of pixels including previously interpolated pixel values and pixel values obtained by line averaging between pixel values in the second and third rows of field pixels. The method further includes interpolating along the selected orientation to determine a value for a pixel to be interpolated.

摘要： Gradient analysis may be utilized to determine frame and field repeat patterns in input video data. Those frame and field repeat patterns may then be analyzed to match them with characteristic patterns associated with telecine 3:2 and 2:2 pulldown video data, for example. In addition, a progressive detector may use combing analysis to determine whether or not a particular field is progressive or interlaced data. Then, this information, together with a field flag which indicates whether field or frame analysis is appropriate, may be utilized to distinguish telecine 2:2 or 3:2 pulldowns and interlaced and progressive data in some embodiments.
