Abstract: In order to solve the problem of target detection in complicated image，image texture features such as geometric figure，gray-value uniformity，edges and measurements etc are analyzed，and a new target detection approach based on texture analysis is presented.Firstly，image edge feature is obtained using the edge detection algorithm based on wavelet analysis.Then after the scanning operation on image using the horizontal template and the vertical，most of background areas in image are excluded，and the coarse range of target is acquired.Finally，the edge analysis algorithm is taken；the accurate range of target is obtained depending on target edge distribution and coarse range of target.The target is detected successfully.Experimental results indicate that it can satisfy the target detection requirements of precision，stabilization and strong anti-jamming.The preciseness rate of detection is up to 99.3％.It is an effective target detection approach and can be used in engineering widely.
