Inputs
Pandora works with two stereo rectified one-channel or multi-channel images.
Configuration and parameters
Pandora input configuration files are divided into two parts: left and right.

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.
For semantic segmentation classification, 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
Parameter left disp can be the disparity range (type list[int, int]) or the path to the grids that contain the minimum and maximum disparity of a pixel (type string).
If left disp is a tuple of integers, then the range of disparities is fixed. The minimal and maximal disparity of the right image are automatically calculated : right disp[0] = - left disp[1] and right disp[1] = - left disp[0] where index 0 correspond to min and index 1 correspond to max.
If left disp is a string, that means it is the path 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 left disp[0] and max for left disp[1]) 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).
Note
- Mask must comply with the following convention
Value equal to 0 for valid pixel
Value not equal to 0 for invalid pixel
Note
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.
Note
The input classification image must have one band per class (with value 1 on the pixels belonging to the class, and 0 for the rest), and the band’s names must be present on the image metadata. To see how to add band’s names on the classification image’s metadata, please see FAQ.
