Binary Mask
Segmentation map of the same size as the input image, where pixels belonging to the object of interest have a value (usually 1) and all other pixels have a null value (0).
Softmax with Cross-Entropy Loss
Standard combination of activation function and loss function for semantic segmentation, where Softmax normalizes prediction scores per pixel into a probability distribution and cross-entropy compares it to the ground truth.
Boundary Refinement
Set of techniques aimed at improving the accuracy of segmented object contours, often using post-processing operations like Conditional Random Fields (CRF) or dedicated edge network modules.
Real-Time Segmentation
Challenge of designing segmentation models that are sufficiently lightweight and fast to process video streams or live sensor inputs, often through model pruning or quantization.
