Abstract

The invention provides an image format conversion method and device, electronic equipment, a computer readable storage medium and a computer program product, relates to the technical field of artificial intelligence such as computer vision and deep learning, and can be applied to an intelligent super-definition scene. According to a specific embodiment, the method comprises the following steps of: acquiring a to-be-converted standard dynamic range image; performing convolution operation on the standard dynamic range image to obtain local features; performing global average pooling operation on the standard dynamic range image to obtain global features; and converting the standard dynamic range image into a high dynamic range image according to the local features and the global features. According to the method provided by the embodiment, when format conversion is carried out, a global average pooling layer is used for directly extracting the global features from the standard dynamic range image, so that the accuracy of the obtained global features is improved, and the quality of the high dynamic range image converted based on the global features is better.

Description

technical field [0001] The present disclosure relates to the field of artificial intelligence, in particular to the field of computer vision and deep learning technology, which can be applied to the intelligent-sensing ultra-clear scene, and in particular to an image format conversion method, device, electronic equipment, computer-readable storage medium, and computer program product . Background technique [0002] As people's pursuit of a better quality of life is increasing, the general public has higher and higher requirements for the quality of media content they watch daily. The synchronous progress of hardware devices has brought high-definition and even 4K videos into the homes of millions of people. [0003] However, most of the media content currently only supports the SDR (Standard Dynamic Range, Standard Dynamic Range) format. Compared with the SDR format, the HDR (High-Dynamic Range) format has increased the number of data storage bits from 8bit to 10bit, and t...
