Figure 5From: Handling missing weak classifiers in boosted cascade: application to multiview and occluded face detection Differences between a cascade and a McCascade when several object detectors must be created. A rough estimate of the execution time is given for each step of the training process. (a) A new cascade must be trained for each new object detector. Each new training can last several hours to several days. (b) A new object detector can be trained using a McCascade. Each training just lasts several minutes.Back to article page
