Abstract: The present disclosure discloses a color matching evaluation method combining similarity measure and visual perception. The method includes: firstly, constructing an image database with rich color information; extracting main colors from an acquired image using an improved clustering method for color matching; generating a corresponding palette using an intelligent color matching recommendation system, and evaluating a palette similarity using a minimum color difference model; then, recoloring the corresponding image using the generated palette through an image recoloring technology to obtain a recolored image, and calculating a structural similarity between the source image and the recolored image; performing feature level adaptive weighted fusion on the palette similarity and the structural similarity, and performing an eye movement tracking experiment on the source image and the recolored image to obtain visual perception data of the images.

Abstract: A server includes a casing, a first disk drive assembly, a fan assembly, a host assembly, a first expansion card assembly, a second expansion card assembly, a power supply assembly, and a second disk drive assembly. The casing has a first to third space. The second space is located between the first and third space. The first disk drive assembly, the fan assembly, and the host assembly are respectively located in the first to third space. The first and second expansion card assembly are located in the third space and above the host assembly. The power supply assembly is located in the third space. The second expansion card assembly is located between the first expansion card assembly and the power supply assembly. The second disk drive assembly is located in the third space and located between the power supply assembly and the second expansion card assembly.

Abstract: The present invention provides a solid-state hard disk lug-in device, including: a main body; a solid-state hard disk installation slot arranged on one side of the main body; and plug-in components. The plug-in components include an operating switch and an operating handle. When the operating switch is closed, the operating handle is restricted to a closed position, and when the operating switch is open, the operating handle is released to an extended position; when the operating handle in the closed position is pushed by an external force, the solid-state hard disk can be inserted into the hard disk slot of the solid-state hard disk system; when the operating handle in the extended position is pulled by an external force, the solid-state hard disk can be pulled out of the hard disk slot.

Abstract: A motherboard including a main circuit board, a first connector, a power circuit board and a second connector. The first connector is disposed on the main circuit board. A periphery of the power circuit board is spaced apart from a periphery of the main circuit board. The second connector is disposed on the power circuit board. The first cable electrically connects the first connector with the second connector.
