Inputs

Pandora works with two stereo rectified one-channel or multi-channel images.

Images

• If the input images are multiband, the band’s names must be present on the image metadata. To see how to add band’s names on the image’s metadata, please see FAQ.

• Only one-band masks are accepted by pandora. Mask must comply with the following convention :

  • Value equal to 0 for valid pixel

  • Value not equal to 0 for invalid pixel

• For more details please see As an API images subsection

Note

• Parameters disp_min and disp_max can be the disparity range (type int) or the path to the grids that contain the minimum and maximum disparity of a pixel (type string).

• If disp_min and disp_max are integers, then the range of disparities is fixed. The minimal and maximal disparity of the right image are automatically calculated : disp_min_right = - disp_max and disp_max_right = - disp_min.

• If disp_min or disp_max are strings, that means they are paths to grids of disparities which have the same size as the input images. Each pixel (x,y) of the grid corresponds to a local disparity (min for disp_min and max for disp_max) related to the same pixel (x, y) of the image.

• Cross-checking step is not applicable if only left grids are provided (i.e the right one must be provided).
