Referring to fig. 2, another embodiment of the method for opening a special-shaped window on a splicing wall according to an embodiment of the present invention includes:
201. the method comprises the steps of obtaining a video image to be subjected to special-shaped processing, cutting the video image by using a preset custom graph, and setting a part outside the custom graph as a background color which is not in conflict with the color of the video image;
firstly, a video image to be processed in a special shape is obtained by a video image processing terminal, then the video image is cut by a preset self-defined graph (for example, the video image is cut by a circular, triangular, elliptical or self-defined irregular graph, and the video image is cut into the circular, triangular, elliptical or self-defined irregular graph), and the part except the video image cut into the self-defined graph is set as a background color which is not in conflict with the color of the video image, for example, the color mainly displayed in the video image is red, namely, the background color can be set as the color with a larger color difference from the color in the video image, such as blue, black and the like according to the visual actual requirement, and the video image processed in the special shape can be obtained.

The video image processing terminal is internally provided with special-shaped processing software which is mainly used for carrying out special-shaped processing on the input video image.
202. Acquiring a video image to be subjected to special-shaped processing, converting the video image into a preset custom image through projection transformation, and setting the part outside the custom image as a background color which is not in conflict with the color of the video image;
meanwhile, for some irregular quadrangles, after the video image to be subjected to irregular processing is acquired by the video image processing terminal, the video image can be converted into a preset custom figure through projection conversion (for example, the video image is converted into the custom irregular quadrangle figure through projection conversion), and the part except the video image converted into the custom irregular quadrangle figure is set as a background color which is not in conflict with the color of the video image, for example, the color mainly displayed in the video image is red, so that the background color can be set as the color with larger color difference from the color in the video image, such as blue, black and the like according to the actual visual requirement, and the video image subjected to irregular processing can be obtained. The video image is put into the special shape, and two putting modes are supported, wherein one mode is that the original video image is directly cut by the special shape, and the video image except the special shape is changed into background color. And for the other type, for the trapezoid, the whole video image can be placed in the video image after being transformed according to the special shape through projection transformation, and the video image except the special shape is changed into the background color.
203. Changing the color of the video image in the user-defined graph, which conflicts with the background color, into a color which is similar to the background color but does not conflict with the background color, and obtaining the video image after the special-shaped processing;
in addition, in order to prevent the color of the video image in the special-shaped window from conflicting with the background color, the conflicting colors in the video image need to be changed into similar and non-conflicting colors during the special-shaped processing. The background color is defined as a special color, that is, the background color is a color within a fixed threshold range of a self-defined color, for example, taking a 24-bit RGB format as an example: 0x000050 can be selected as the background color, and meanwhile, the background color judgment threshold is set to be 0x10, namely, the values of 0x 000040-0 x000060 are all considered as the background color. Meanwhile, by taking the background color set on the upper surface as an example, if the blue color between 0x000040 to 0x000060 appears in the video image in the special-shaped window, the judgment is firstly made to be more than 0x000050 or less than 0x000050, namely the color between 0x000040 to 0x000050 of the video image in the special-shaped window is changed into 0x000035, and the color between 0x000050 to 0x000060 of the video image in the special-shaped window is changed into 0x 000065.
204. Inputting the video image after the special-shaped processing into a splicing wall for video processing;
and after the video image after the special-shaped processing is obtained, inputting the video image after the special-shaped processing into a splicing wall for video processing. Because the video image after the special-shaped processing is still a rectangular video signal and is only the background color outside the video image, the video processor of the splicing wall can perform special-shaped window opening display after the obtained video image signal after the special-shaped processing is cut, scaled, spliced and the like according to the rectangular video signal.
