Inputs

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

left_mask	Path to the left mask	string	none	No
right_mask	Path to the right mask	string	none	No
disp_min_right	Path to the minimal disparity grid of the right image	string	none	No
disp_max_right	Path to the maximal disparity grid of the right image	string	none	No
left_classif	Path to the left classification map	string	none	No

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).

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.
