I look at your example, the picture is the .bgm, how about the .jpg and .bmp?
hello, i like to use your opensource to my research but i don't know what is keypoint coordinate in image coordinate, can you please tell me?
Hi,
I'm interested in using ezSift within a Java application which will be deployed later on a windows + linux machine. Is there any executable or lib file that I can call from within java code?
Thanks in advance.
Thank you for your well-commented program. I learned a lot from them.
I have a question about a line of code. In ezsift.cpp, line 218
gaussian_coefs[i][j] = expf(tmp * tmp * -0.5f) * (1 + j / 1000.0f);
I notice you have multiplied the exponential with a factor (1 + j / 1000.0f). Why would we need that, it seems will cause the gaussian kernel asymmetric any more?
the picture size is 4096*3000

void Image::init(int _w, int _h)

w = _w;
h = _h;
data = new T[w * h];
}
0x75CAA6E2 处(位于 31.SIFT_ZYX.exe 中)有未经处理的异常: Microsoft C++ 异常: std::bad_alloc,位于内存位置 0x0135F718 处。
Is it because the picture is too big?How to solve it?
