摘要: An image collection device for light splitting and fusion is provided. In the image collection device, a light splitter splits incident light into a visible light and a non-visible light; a visible spectrum imaging module performs photosensitive imaging according to the visible light split by the light splitter to form a first visible light image; a non-visible spectrum imaging module performs photosensitive imaging according to the non-visible light split by the light splitter to form a first non-visible light image; a registration unit performs position registration on the first visible light image and the first non-visible light image to obtain a target visible light image and a second non-visible light image; a pre-processing synthesizing unit performs brightness adjustment on the second non-visible light image to obtain a target non-visible light image; a fusion unit performs image fusion on the target visible light image and the target non-visible light image to obtain a fused image. By this solution, the color accuracy of the fused image can be ensured effectively.

摘要: Embodiments of the invention provide a method for scene understanding based on a sequence of image frames. The method comprises converting each pixel of each image frame to neural spikes, and extracting features from the sequence of image frames by processing neural spikes corresponding to pixels of the sequence of image frames. The method further comprises encoding the extracted features as neural spikes, and classifying the extracted features.

摘要: A plurality of video images indicated by a plurality of video data each having different color gamuts are displayed on one screen in colors each close to the colors of original video images. A color gamut specifying unit (34) specifies a color gamut to which each of the plurality of video data conforms. A video processing circuit (14) converts the plurality of video data into display data including the plurality of video images to be displayed on one screen of a display unit (15), and also performs conversion into the display data conforming to a color gamut of the display unit (15) on the basis of the color gamut specified by the color gamut specifying unit (34).

摘要: Compared to traditional gamma-coded video, perceptually quantized video provides greater flexibility for the transmission and display management of high-dynamic range video, but it does not compresses as efficiently using existing standard codecs. Techniques are described to improve the coding efficiency of perceptually coded video by applying a color cross-talk transformation after the RGB/XYZ to LMS transformation. Such a transform increases luma and chroma correlation for color appearance models, but improves perceptual uniformity and overall coding efficiency for wide color gamut, HDR, signals.

摘要: A real-time color mapping system includes a memory and a converting module. The memory is configured for storing a mapping table. The converting module is configured for reading the mapping table stored in the memory, and for converting first image grayscale values corresponding to a first image signal into second image grayscale values corresponding to a second image signal according to the mapping table. The converting module utilizes at least part of bits corresponding to each of the first image grayscale values as a memory address to look up in the mapping table, thereby converting the first image grayscale values into the second image grayscale values. A real-time color mapping method is provided herein as well.
