Combining where and what in change detection for unsupervised foreground learning in surveillance
作者:
Highlights:
• Build multi-appearance detectors for unknown and uncontrolled sequences in unsupervised manner.
• Global discriminative optimization based on latent SVM is able to build accurate multi-class detectors without pretrained detectors.
• From a noisy initialization (motion cues) learn position, scale and appearance of multiple foreground objects.
• Combine in an unsupervised way where (motion segmentation) and what (learning procedure) in change detection.
• Handle an unknown number of objects in an unconstrained scenario.
