The invention provides a color value obtaining method and device and a spatial compound imaging method and device. A color value calculating method comprises that a neighbor pixel point satisfying a preset neighborhood condition is determined for a to-be-solved pixel point in a to-be-solved image; according to the distance from the neighbor pixel point to the to-be-solved pixel point, a weight value of the neighbor pixel point relative to the to-be-solved pixel point is determined; and according to the weight value as well as a color value of the neighbor pixel point, a color value of the to-be-solved pixel point is calculated. According to embodiments of the invention, high-frequency information of original collection signals can be reserved as possible while it is ensured that the to-be-solved image is smooth and continuous, and the contrast resolution of the to-be-solved image is improved. Computational complexity in calculating the color value of the image can be reduced.
Description
Technical field [0001] This application relates to the field of image processing technology, and in particular to a method and device for obtaining image color values, a method and device for spatial composite imaging, and a scan conversion method and device for ultrasound imaging. Background technique [0002] The color value of an image refers to the color depth of the pixels in the image. If an image is a black and white image, the color value is the gray value. The gray value generally ranges from 0 to 255, with white being 255 and black being 0, so black-and-white pictures are also called gray-scale images, which are widely used in the fields of medicine and image recognition. In the process of capturing images by various medical equipment, the coordinate positions of the pixels of the initially collected image are often different from the coordinate positions of the pixels that need to be displayed in the image. For example, the collected coordinate positions are irregular ...
