    Abstract: A method of calculating discontinuity of a motion vector includes obtaining at least any one of a k-th projected forward motion vector by a forward motion vector of a block and a k-th projected backward motion vector by the forward motion vector and at least any one of a k-th projected forward motion vector by a backward motion vector and a k-th projected backward motion vector by the backward motion vector; obtaining inconsistency of forward motion vector to k-th frame projection and inconsistency of backward motion vector to k-th frame projection by calculating a first difference function using the obtained vectors, and calculating discontinuity using the inconsistency of forward motion vector to k-th frame projection and the inconsistency of backward motion vector to k-th frame projection.

    Abstract: An image displaying system includes: a display device, a detection device and an image compensating chip. The detection device obtains position information of a view point relative to the display device, and an angle of sight line; the image compensating chip divides equally the image to be displayed into a plurality of first sub-images along a first reference direction, calculates a compensation ratio along the first reference direction for each first sub-image, and compensates each first sub-image along the first reference direction; the first virtual section line segment has two endpoints located on the frame of the display device, is extended along the first reference direction, and passes through an intersection of the sight line and the display device; the display device displays the compensated image, so that the compensated first sub-images are viewed as having the same size along the first reference direction.

    Abstract: The present invention discloses a contrast adaptive video denoising system, which comprises a frame memory for buffering the filtered frame; an inter-frame difference calculating module for inter-frame difference of the current input frame of the video and a previous filtered frame in the frame memory; a contrast calculating module for calculating the local contrast of the current input frame and inputting it into a low-contrast region detection module, a calculated low-contrast region confidence together with the inter-frame difference are input into a motion detection module to calculate the motion probability for each pixel. The motion adaptive temporal filtering module performs motion adaptive temporal filtering by using the current input frame of the video and the previous filtered frame in the frame memory as well as the motion probability of each pixel, and finally outputs the current filtered frame to store in the frame memory. Said system can solve the problems of motion tailing and blurring caused by conventional video denoising systems when processing low-contrast motion videos.
