User Guide On Blending
Blending
The stitcher has the capability of blending the limit between two adjacent images to hide the abrupt change of color and gain between the input images. The parameter to adjust this feature is called border-width, and is the number of pixels to blend.
The border-width is measured from the start of the overlap between two images as shown in the image below.
It is also worth mentioning that the blending is only processed over an overlapping area; in other words, if the blending width is larger than the overlap, it will be the same as processing a blending width the same size as the overlap; that is without affecting performance.
