Image Classification Using Fisher Vectors Perpetual Enigma

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 FV … 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 Information retrieval The Fisher kernel is the kernel for a generative probabilistic model. As such, it constitutes a bridge between generative and probabilistic … See more Fisher score The Fisher kernel makes use of the Fisher score, defined as $${\displaystyle U_{X}=\nabla _{\theta }\log P(X \theta )}$$ with θ being a set (vector) of parameters.
