The video signal from the camera, that is shooting the performing player on the stage, is sent to SGI computer, and DIPS objects in Max patches transform those images. The transformed output images from the computer are projected on the screen behind the stage simultaneously.
See full list on docs.opencv.org III: Image blending. Here is a quick presentation of the blending function we implemented in the function histoeq_blend(). The idea here is to mix two images to get a good compromise between a too dark image and a too bright image obtained after histogram equalization. image stitching as a multi-image matching problem, we can automatically discover the matching relationships between the images, and recognise panoramas in unordered datasets. Thirdly, we generate high-quality results using multi-band blending to render seamless output panoramas. This paper extends our earlier work in the area [BL03] by introducing
To create the Sample Images shown in the Blend Type and Filter Type tables, an image is used in the background, with a shape layered on top that contains the Blend or Filter type. The Blend Types, in particular, work by evaluating the colors of both the background and foreground objects and then blending those colors for the composition.
