Fig. 3From: Inter/intra-frame constrained vascular segmentation in X-ray angiographic image sequenceComparison of the extracted vascular images on six randomly selected images from six different sequences by four methods. (a1-f1): original XRA images; (a2-f2), (a3-f3), (a4-f4) and (a5-f5): extracted vascular images by MER, ORPCA, MCR-RPCA and IFC-RPCA methodsBack to article page
