VEIN FEATURE EXTRACTION METHOD AND APPARATUS IN LEAF IMAGE

摘要

Disclosed are an apparatus and a method for detecting a vein and extracting vein features from a leaf image. The apparatus and the method comprises the following steps of: inputting a leaf image using a photographing device of a computer or a mobile terminal; detecting a vein area in the leaf image by the processor of the computer or the mobile terminal; detecting, by the processor, a vein in the vein area and obtaining an vein image of the detected vein; detecting, by the processor, the main vein of the vein by horizontally projecting the vein image; determining, by the processor, the direction of the vein by perpendicularly projecting the vein image; and thinning the vein and extracting the features of the vein by the processor. As a result of the automatic processes from image input to leaf feature extraction, the apparatus and the method have efficient and high leaf recognition performance.
