摘要： A video signal coding system employing a segmentation technique segments a video frame signal into regions to generate contour and texture information of each region and detects continuous boundaries located between adjacent regions. The contour and the texture information of each region and the boundary information of the continuous boundary are encoded to provide an encoded video signal. The video signal coding system calculates a mean value of pixels in two adjacent regions of each side of a continuous boundary and updates each pixel value within a predetermined distance from a continuous boundary with the mean value.

摘要： An apparatus for predicting a current frame signal included in an image signal based on a reference frame first detects a panning vector representing a spatial displacement between the current and the reference frames. Once the panning vector is detected, a predicted frame containing a substitutable region and an unsubstitutable region is determined based on the panning vector and the reference frame, and then an amplitude of the panning vector is compared with a reference value. Subsequently, a predicted current frame signal is generated as the result of the current frame prediction process in response to the result of the comparison. If the amplitude of the panning vector is smaller than the reference value, the predicted current frame signal is produced by padding pixel values of the substitutable region which are located along a boundary between the substitutable region and the unsubstitutable region into the unsubstitutable region. Meanwhile, if the amplitude of the panning vector is greater than or equal to the reference value, the predicted current frame signal is created by using a block matching technique for the unsubstitutable region based on the current and the reference frame signals.
