9 months ago Hi, @molong-d.
After feature extraction,i want to use HPatches-Sequences-Matching-Benchmark to analyze data results.I will decompress the resulting file and extract descriptors.npy and keypoints.npy. Rename it to ORB.npy and place it in the cache folder.
The npy file is the result of HPatches evaluation, you don't need to create it by yourself. You just need to extract the feature following the instructions in feature-extraction. Then run the HPatches-Sequences-Matching-Benchmark.ipynb, and you can get the results in this jupyter notebook and the npy file in the cache folder.
Sorry for the late reply. Hope it helps.

Hello, thank you for sharing your excellent work. Let me ask the code about HPatches-Sequences-Matching-Benchmark. After feature extraction,i want to use HPatches-Sequences-Matching-Benchmark to analyze data results.I will decompress the resulting file and extract descriptors.npy and keypoints.npy. Rename it to ORB.npy and place it in the cache folder. But I encountered the following code error.Could you please help me check this error message. Did I make a mistake, but I really don't understand what file is needed as input for the HPatches Sequences Matching Benchmark ipynb code?
Please help me, thank you very much
