基於模糊拓撲的圖像區域目標提取方法
The invention relates to a method for extracting an area target of an image based on fuzzytopology, which comprises the following steps: an original image is treated in advance; an optimal threshold value T is dawn into; an object to be extracted is defined as a fuzzytopology object; the optimal threshold T is used for inducing two threshold values T1 and T2; regional division is carried out on the object to be extracted; and finally, the object is extracted out. In the method, the two threshold values are dawn into by a fuzzytopology method for determining the interior, boundary and externalof the object to be extracted, thus improving extracting quality to a certain degree; fuzzytopology connexity is carried out on boundary pixels so as to determine whether belong to the extracting range; a part duality mole (LBP) functor is dawn in in the analyzing process so as to increase judgment precision; in addition, the method for extracting the area target of the image based on fuzzytopology can significantly the extraction precision of the object, the boundary pixels of which is more difficult to be judged, thus obtaining better extraction results.
