property class_probabilities_map

Pointer to the raw array containing the probabilities. The probability for class c and pixel (x,y) will be at index (c * width *height + y * width + x).

property classes

Number of classes in the segmentation output.

property height

Height of the segmentation output class map.

property priv_data
