The input images definitely need to be partitioned into training and validation parts. One more thing: Fisher vectors are ... 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.
