【CV论文阅读】An elegant solution for subspace learning

Pre:

It is MY first time to see quite elegant a solution to seek a subspace for a group of local features. I list two related papers for your reference: “Local Feature Discriminant Projection” and “Binary Set Embedding for Cross-Modal Retrieval”. This post is just a note which might leave out some important details and information. Following I will first introduce the LFDP algorithm then the BSE algorithm for cross-modality learning.
