4 results about "Image conversion" patented technology

The invention discloses a medical image enhancement method, which is realized based on a bidirectional generative adversarial network architecture. The architecture comprises two generator/discriminator pairs, and generator learning converts an image in a low-quality image domain or a high-quality image domain into a corresponding image in the high-quality image domain or the low-quality image domain. A discriminator distinguishes a real image in a low-quality image domain or a high-quality image domain from an image converted from the real image in the high-quality image domain or the low-quality image domain, the architecture introduces constraint terms in an objective function of a bidirectional generative adversarial network, and the constraint terms include an illumination regularization term and a structure loss term. The invention provides a novel medical image enhancement frame, and the imaging quality of the medical image is improved.

The invention provides a high-speed rail station intelligent lighting system and an omnibearing lighting lamp. The system comprises an image acquisition module used for acquiring a first to-be-spliced image; an image conversion module which is used for detecting the safety line linear equation and obtaining a second to-be-spliced image. a region similarity judgment module which is used for generating a topological graph according to the relationship of the closed regions, obtaining node similarity according to the similarity of color values, position features and structural features of the nodes at the same level, obtaining matched node pairs, and detecting ground pixels to obtain a third to-be-spliced image. a complete splicing module which is used for calculating the color overlap ratio and the safety line overlap ratio, finding an optimal splicing position and splicing to obtain an optimal spliced image; an illumination module which is used for segmenting a safety line image from the optimal spliced image, detecting whether a safety line is shielded by a foot key point or not, and carrying out illumination reminding by using an omnibearing illumination lamp.
