Abstract

The invention discloses an image reconstruction method for a cross-modal communication system. The method comprises the following steps: reconstructing a missing image in a transmission process through employing a complete tactile signal received by a receiving end in the cross-modal communication system, and constructing a cross-modal interaction network in combination with an attention mechanism. The limitation that a traditional generation model can only train paired samples is solved. The invention further discloses an image reconstruction device for the cross-modal communication system. According to the method, the semantic correlation among different modal data is fully utilized. The cross-modal generation from the tactile signal to the image is realized for unpaired data. The problem that practical training tactile signal-image data is difficult to acquire in pairs in a cross-modal communication system is solved. The quality and the category precision of the generated image are remarkably improved.

Description

technical field [0001] The invention relates to the field of cross-modal image generation, in particular to an image reconstruction method and device for a cross-modal communication system. Background technique [0002] Cross-modal communication is a new type of communication technology that aims at the coordinated transmission and joint processing of visual, audio, and tactile signals. It supports cross-modal multimedia services and has the characteristics of multi-dimensional integration and richer immersive sensory experience. However, in the process of cross-modal communication, there are often problems such as limited transmission capacity and transmission interference, which cause the image data received by the terminal to be blurred or even completely lost. [0003] Aiming at various interference factors in the transmission process, relevant scholars have proposed a series of image restoration methods. For example, in order to remove the impulsive noise in image rest...
