Fisher vector 설명
The Fisher kernel can result in a compact and dense representation, which is more desirable for image classification and retrieval problems. The Fisher Vector (FV), a special, approximate, and improved case of the general Fisher kernel, is an image representation obtained by pooling local image features. The … See more In statistical classification, the Fisher kernel, named after Ronald Fisher, is a function that measures the similarity of two objects on the basis of sets of measurements for each object and a statistical model. In … See more • Fisher information metric See more Fisher score The Fisher kernel makes use of the Fisher score, defined as See more Information retrieval The Fisher kernel is the kernel for a generative probabilistic model.
