The application discloses a kind of based on optimization's guiding filter image fusion change detection method and device, method includes: by extreme minimum scale difference operator, pixel value difference value is to the picture of same scene different phase, obtains difference map;Using the way of guiding filter, difference map is fused on global scale, to obtain the optimal difference map;Mean filter is used to phase map I1 and I2, and the base layer difference map corresponding to each difference map is obtained, and the optimized brightness saliency map F1 and F2 are obtained by pca fusion as the image of generating saliency map, according to the principle of maximum saliency to determine weight map;Weight map is regularized for double-scale difference map reconstruction, and the final difference map is obtained;In clustering segmentation stage, by introducing soft threshold function, the final difference map is further processed, to suppress existing abnormal noise.The device includes: processor and memory.

The present invention relates to the technical field of image processing, and discloses a color denoising method for autonomous driving images, which is characterized by: being applied to road images during vehicle driving, including preprocessing the images with a point-by-point sliding window filtering method, suppressing outlier color points and color clusters, and obtaining a preprocessed image; performing multi-channel step-by-step decomposition of the preprocessed image with the aid of a multi-channel filter to obtain a multi-scale sub-band image; and performing joint filtering and reconstruction on the multi-scale sub-band image in succession to obtain a final denoised image. With the aid of the image color denoising method of the present invention, low-frequency color noise can be effectively reduced, which is more conducive to the recognition of traffic signal signs by the autonomous driving perception module, thereby greatly improving the subsequent decision-making stage.

The invention discloses a gravure printing plate and a gravure printing machine. The gravure printing machine comprises an impression cylinder and the gravure printing plate. The gravure printing plate comprises at least one electrode printing unit, and the gravure printing plate can be arranged in a cylindrical shape; the electrode printing unit comprises a main body part and a first edge part, and the main body part is rectangular. A first edge part is arranged on at least one of the two side edges, in the first direction, of the electrode printing unit, and the first edge part comprises at least one first concave area distributed in the first direction at intervals; the recess depth of the first recess region is 12 to 20 [mu] m. The gravure printing plate can ensure that the pattern edge of the electrode is complete, slurry is prevented from overflowing, slurry accumulation is reduced, and the reliability of electrode quality is improved. The method can be widely applied to the technical field of intaglio printing.
