Figure 4From: A new efficient active contour model without local initializations for salient object detection Comparison between the different active contour models. (a) First column - original grey-level images with initial active contours (represented by white lines), (b) second column - segmentation results using gradient-based active contour, (c) third column - segmentation results using region-based active contour of [31], (d) fourth column - segmentation results using region-based active contour of [30], and (e) fifth column - segmentation results using polarity-based active contour.Back to article page
