Three-dimensional (3D) crystal inside-carven photo frame

The invention discloses a three-dimensional (3D) crystal inside-carven photo frame. The 3D crystal inside-carven photo frame comprises two crystal glass blocks provided with three-dimensional laser engraving patterns in the insides and is characterized by further comprising a base and a fixing frame with two opened ends, wherein the bottom of the fixing frame is embedded into the center of the base, a limiting block is arranged on the bottom face of the fixing frame, and the limiting block and the bottom face of the fixing frame are connected onto the base through countersunk head screws. The two crystal glass blocks are respectively located on two sides of the fixing frame, and the end portions of the two crystal glass blocks are located in the fixing frame. A light source is arranged on the limiting block. The 3D crystal inside-carven photo frame has the advantages that firstly, the two crystal glass blocks provided with the three-dimensional laser engraving patterns in the insides are fixed on the base through the fixing frame, and the width of the base is large, so that the photo frame does not easily fall down; secondly, the light source is located in the fixing frame and located between the two crystal glass blocks, and light produced by the light source is diverged towards two sides and can enable images in the crystal glass blocks to be shown clearly.

Dark image enhancement method based on Retinex

PendingCN113344798AAdd depthCompatible with human visionImage enhancementImage analysisFeature mappingHuman eye
According to the dark image enhancement method based on Retinex, an image is converted from an RGB image to an HSV image, and the method is more in line with human vision. All the layers are directly connected together. In the novel architecture, the input of each layer consists of the feature mapping of all previous layers, and the output of each layer is transmitted to each subsequent layer. The feature maps are aggregated by a deep cascade. The depth of the neural network is improved, and the gradient disappearance problem is solved. An original network is up-sampled at the tail end of the network by using a nearest neighbor method to achieve a high-resolution size, compared with the original network, the improved EnhanceNet network adopts a bilinear interpolation up-sampling method, and by adopting the method, learning is not needed, the running speed is high, and the operation is simple. Only a fixed parameter value needs to be set, and the set parameter is a coefficient which needs to be multiplied by the central value. And compared with the original nearest neighbor algorithm up-sampling, the new up-sampling method can display the image more clearly, and the network effect is further improved.
