摘要： A method of point cloud coding (PCC) including receiving encoded patch information data; obtaining a patch corresponding to the encoded patch information data, the patch having a patch type; determining whether the patch type for the patch is a last patch type; and terminating a reconstruction process corresponding to the encoded patch information data when the patch type is the last patch type. Another method includes the same receiving and obtaining steps, but determining whether the patch type for the patch is a skip patch type; decoding a reference patch index corresponding to the patch when the patch type is the skip patch type; determining a reference index for the patch based on a reference frame index corresponding to the patch and the reference patch index as decoded when the patch type is the skip patch type; and reconstructing a volumetric representation of the patch.

摘要： A method performed by an electronic device is described. The method includes obtaining a motion vector map based on at least two images. The motion vector map has fewer motion vectors than a number of pixels in each of the at least two images. The method also includes obtaining a feature point from one of the at least two images. The method further includes performing a matching operation between a template associated with the feature point and at least one search space based on the motion vector map. The method additionally includes determining a motion vector corresponding to the feature point based on the matching operation.

摘要： Images are obtained for image compression. The images are compared using sum of absolute difference devices, which have arithmetic parts, and accumulators. The sign bits of the accumulators are determined at a time of minimum distortion between two images. These sign bits are associated with sets of probabilistically-similar parts. When other sets from that set are obtained later, an early exit is established.

摘要： During digital video signal processing, the knowledge of position and time modifications in the recorded scene is utilized for data compression and format conversion. In general, expensive computer circuits are necessary for conducting high-precision estimation of motion. The inventive hybrid method comprises simple measures which can be clearly executed and provide a low-cost high-precision estimation of motion. According to the invention, a block vector BV is generated in a number of steps for each block. To begin with, a first modified block matching occurs in order to select a start vector SV from a number of vector candidates VCi. The start vector SV is then refreshed by pixel recursion and used as an additional start vector VCi+1. Finally, a block matching resulting from coordinating the first and second steps in a third step produces the final block vector BV. The block vectors BV are read out for a successive generating of a dense motion vector field and for new vector candidates VCi which are to be intermediately stored.

摘要： An electronic device that efficiently compresses a large volume of data included in a broadcast signal and stores the compressed data is to be provided. The broadcast signal is decoded and decompressed through a tuner and a set top box (STB), and a signal (image data) that is decoded and decompressed is inputted to a video display device, so that an image based on the signal is displayed. As a unit for efficiently compressing and storing the image, an electronic device including an encoder, a decoder, and a memory device is used. An image data outputted from the tuner and the STB is compressed using the encoder, and the compressed data is stored in the memory device. To reproduce and display the image data, the compressed image data is decompressed by the decoder, and the decompressed image data is inputted to the video display device. For the compression of the image data in the encoder, an analog processing circuit included in the encoder or a semiconductor device in which a neural network is constructed is used.
