sift for dummies

Sift,the scale invariant Feature Transform, the invariant feature transform is an effective method to detect the uniqueness of images, to translate, rotate, scale and even affine transformations (such as taking pictures from different angles) to maintain invariant image local features. It can be easily applied to image matching applications, such as target detection and recognition, or the calculation of geometric transformations between images.The al

C-language dummies (1): nested loops-program structure, dummies Loop statement nesting a loop structure can contain another loop, called loop nesting, or multiple loops. The nested loop is a double loop. The outer loop is called an external loop, and the inner loop is called an internal loop. --------- I don't know where the basic concepts come from 　　 　　This is the first blog of the baby.

Sift is a very classical algorithm for image matching, but very complicated, want to own C or C + + implementation is very troublesome, if just use, there are some foreign high maintenance of SIFT library, the early stage as long as they can call, the key is to be familiar with the general flow, the SIFT library has an understanding, The exact work is done by sim

Today is a coincidence to find the same outline of the nature of the article.If only we could find it earlier. However, "When you think it is too late, in fact, it is not too late" can also be consolation, but can not often confuse themselves, after all, I need to start running!Follow this outline to go down, perhaps there will be unexpected gains, and then put the problem of multi-perspective, perhaps it should be effective.Well, it's useless to want too much of anything else.I think the more i
