This application provides a method for adding watermarks to an image. Belonging to the field of information security, this method involves dividing an image into blocks to obtain a target number of non-overlapping blocks. The texture complexity is determined based on the number of pixels at the block boundaries and the size of the blocks. The watermark embedding amount is determined based on the texture complexity of each block, the average watermark embedding capacity, and the initial texture complexity. The average watermark embedding capacity is determined based on the total watermark information capacity and the target number. Singular value decomposition is performed on each block to obtain the maximum singular value. The singular value after watermark embedding is determined based on the maximum singular value of each block and the watermark information corresponding to the watermark embedding amount. Inverse singular value decomposition is performed on the singular values ​​after watermark embedding in each block, and each block after watermark embedding is reconstructed to obtain a watermarked image. This method can improve the amount of watermark information and the quality of the watermarked image.

The application discloses a kind of zero visual seam's liquid crystal display unit, it is related to display technical field.The display unit includes backlight module, liquid crystal panel assembly and optical compensation composite cover plate.Wherein, the edge of backlight module is equipped with the chamfer support surface that is inwards shrinkage, the non-display area of liquid crystal panel assembly is bent or adhered along the chamfer support surface, so that the physical height of non-display area is lower than the plane where effective display area is located.Optical compensation composite cover plate is adhered to the surface of liquid crystal panel assembly and extends to cover above non-display area, and the cover plate sequentially includes light remodeling layer, waveguide light uniform layer and wide-angle scattering layer from bottom to top.The application is cooperated by mechanical structure and micro-nano optics, realizes the visual screening of physical seam under the premise of not increasing electronic control complexity, solves the problems of large assembly thickness, black seam ghost and edge image distortion in traditional seam elimination scheme.

This utility model relates to the field of vehicle manufacturing technology, and more particularly to a door assembly and a vehicle. The door assembly includes: an outer door panel, an inner door panel, an upper reinforcing plate on the outer panel, and a lower reinforcing plate on the outer panel. The upper reinforcing plate on the outer panel is connected to the outer door panel, and the lower reinforcing plate on the outer panel is connected to the inner door panel. The inner door panel is fastened to the outer door panel, and the upper reinforcing plate on the outer panel is connected to the lower reinforcing plate on the outer panel. According to this utility model, the inner door panel and the lower reinforcing plate on the outer panel are connected to form a module, and the outer door panel and the upper reinforcing plate on the outer panel are connected to form a module. This allows for assembly of the door assembly simply by fastening the inner and outer door panels together, reducing the assembly difficulty, improving the overall structural strength and rigidity of the door assembly, and enhancing the assembly efficiency and quality.

This invention discloses a single-lock curtain wall with a non-intrusive clamp hoisting component and its construction method, belonging to the field of building curtain wall technology. It solves the technical problems of traditional post-installed embedded components damaging the main structure, difficult rebar installation, low installation accuracy, and poor adaptability. The single-lock curtain wall includes a post-installed clamp assembly, a beam structure, a reinforced load-bearing component, a hoisting cable assembly, and a curtain wall assembly. The post-installed clamp assembly consists of a load-bearing plate, a tie plate, a reinforcing plate, and a hoisting plate. It forms a ring-shaped non-intrusive structure by bonding and welding with architectural AB adhesive. Combined with the differentiated reinforcement structure of the beam structure, it achieves uniform load transfer. The construction method includes on-site material customization, non-intrusive installation of the clamp assembly, precise curtain wall suspension, and intelligent monitoring with a total station. The monitoring system captures millimeter-level displacement through a prism, forming a closed-loop control of measurement-feedback-adjustment.
