2018-06-08 03:56:16 -0600 | marked best answer | How to search for near identical images? I want to implement an image DB. If i've got it correctly, I need to use BoW and then I would be able to classify a new image if I have seen it before. But all examples I have seen nefore (e.g. this) have some set of traning images, when training is done then BoW is using to classify the rest. My situation is different: I have to search through the BoW for an image, and if there is no match then we consider it to be a new image, otherwise we don't add it and say "already exist". Skewed, rescaled and others images should be considered the same, so I used SIFT as a feature detector. So the problem in a nutshell: At beginning, I have an empty database of images (so I have no data to train on). I have a stream of images. I can calculate features of this image. Then I have check if there is some images which descriptors match descriptors of this image more than some treshold then I say "existing", otherwise I add these descriptors as a new image and return "new image". If I get the same image (or similar image) in future I say "existing". It requires rebuild BoW with every new image, which seems to be a very complicated solution. All search engines on the internet are doing this so I'm surprised there is almost no information in the web. Okay, I tried to use Then I run the test on following images: So PHash.compare gives distance The entire code is available here and here Test code: (more) |

2018-03-01 03:43:31 -0600 | marked best answer | Is C API alive or not I want to write a wrapper for OpenCV using different language. For obsious reasons I can only use C API. And I have two alternatives: write my own wrappers over C++ code and expose it OR I can take existing C API, but the drawback of this approach is my fear that C bindings may be abandoned. I'm starting a new shiny project, but I don't want to write extra C code when I can reuse existing one. Or I can't? Because as I see multiple functions are missing, even very basic ones, like |
