GoWebScanVisionResampler Class Reference
Description
Represents an algorithm for producing uniform-resolution resampled vision output given input terrain and demosaiced color vision tiles.
Algorithm steps:
- When processing an input image, each of the output rows that fall within its Y-location limits is considered. Output rows that fall within this region are processed one at a time; if the row has not been previously considered, its pixels are first cleared.
- For each pixel in a particular output row, the corresponding terrain Z value is first looked up.
- Using the xRes(z) and yRes(z) functions provided by GoWebScanConfigNode, and the known terrain Z value, the image resolutions are calculated. Using the image X-center (GoWebScanConfigNode), image Y-center (image stamp), and Y-offsets (GoWebScanConfigNode), the address of the input pixel that best matches the location of the desired output pixel is calculated.
- When input images overlap, the pixels from each image are averaged together in the output buffer. This implies that rows in the output buffer should be retained until the trailing Y-location limit of the next input image is known; rows prior to the limit will no longer be modified and can be emitted.
