thank for answer images size are same.but the left picture has cropped and zoomed.it not seems that have effect on result. i think that matlab code is correct but in result of opencv is not good i need a correct opencv code about Sift image matching

hi guys i trying sift matching in opencv and got bad result , but with same picture in matlab result is excellent...why ??? image description

in above picture , left picture is output of opencv sift matching and in right sift matching by matlab pictures is equal and output is different...

is there anybody to help me ???? thank a lot

2016-05-26 08:41:52 -0500 asked a question Problem with SIFT Image Matching

hi guys i am working on vehicle type detection(for example detect BMW) uses Sift algorithm and OPENCV i uses image matching and i make a Pattern (front car) and compare this pattern with other input image i have a problem

this algorithm just find same pattern in input image and cannot find similar car in image please give me idea

i test a pattern by Matlab on this attachment picture please see itimage description

hi adamIB

i try to install opencv3 for my project with extra module (i want to use sift algorithm for image processing) but i cannot configure cmake with contrib (contain feature2d) ..i got error "CMake Error at cmake/OpenCVModule.cmake:277 (add_subdirectory):

The binary directory C:/opencv/build/modules/calib3d/.calib3d" and for other modules "core,cudaarithm,cudabgsegm,cudacodec,cudacodec,cudafeatures2d,cudafilters,cudaimgproc,cudalegacy,cudaobjdetect,cudaoptflow,cudastereo,cudawarping,cudev,features2d,flann,highgui,imgcodecs, etc.)

for example recognition from front of vehicle (car) ....excuse me for bad english typing....
