Abstract: A low-complexity panoramic video coding method considering distortion temporal propagation is provided. By analyzing the inter-frame reference relationships under the random access coding structure and establishing the corresponding distortion propagation chain, the method utilizes distortion impact factors of coding units to adjust encoding parameters, thereby optimizing the encoding process. Furthermore, the method addresses the issue of oversampling arising from the varying geometric deformations in different latitude regions during the projection of spherical images in panoramic videos. This is achieved by adjusting coding parameters based on the ratio of area changes at different latitudes. The proposed approach significantly enhances coding performance.

Abstract: An image processing method includes converting an original image represented by a first color space into the original image represented by a second color space, where a correlation between color components of respective channels in the second color space of the original image is smaller than a correlation between color components of respective channels in the first color space; denoising channel images formed by the color components of the respective channels in the second color space respectively to obtain denoised images corresponding to the respective channel images; and obtaining a target image based on the denoised images.

Abstract: A detachable quick-freezing food storage case is provided that includes a storage case body and a quick-freezing fan assembly. The quick-freezing fan assembly comprises a quick-freezing fan support and a quick-freezing fan. The quick-freezing fan support includes an air inlet positioned proximate the quick-freezing fan. The storage case body includes a return air inlet. The quick-freezing fan support surrounds one of the air outlets on a cold air duct board to form an air circulation path from the air outlet, through the air inlet, to the return air inlet. The storage case body also includes a cover fitting the storage case body. The quick-freezing fan is connected to a main control panel, and the main control panel is connected to a display control panel. The storage case is also detachable, making it convenient for customers to use refrigerator space efficiently.
