Abstract

The present invention relates to a vibration tactile encoding and decoding method based on deep learning, which specifically includes the following steps: jointly encoding different dimensional data of the tactile signal, removing the redundancy existing in the three-dimensional space of the tactile data, and preprocessing it at the same time; The control cycle unit network GRU is trained, and each time two sets of data are input to obtain the predicted data of the next set of data, and the real value of the next set of data is used as a label, and the predicted data is compared with the real data to calculate the residual pair prediction The data is compensated to obtain the reconstructed forecast data; the reconstructed forecast data is packaged with the previous set of data and used as the input data for the next round of forecast. Compared with the prior art, the present invention has greatly improved performance.

Description

technical field [0001] The present invention relates to the technical field of video coding, in particular to a vibration-tactile coding and decoding method based on deep learning. Background technique [0002] Current research on tactile information has not reached the same high-quality level as auditory information. In particular, compared with audio and video, the development technology of tactile codec still has a considerable distance, and further research is needed in design and optimization. Therefore, it is very necessary and urgent to design a haptic codec that can significantly reduce the data rate and achieve high fidelity and low latency at the same time. [0003] At present, the tactile codec design scheme is mainly divided into two categories. The first category is the tactile coding and decoding algorithm based on the human tactile perception physiological theory. Compression algorithm to the frequency domain. Contents of the invention [0004] In view of...
