Fisher kernel image processing

WebJan 8, 2024 · Abstract. Fine-grained image categorization is a categorization task, where classifying objects should be the same basic-level class and have similar shape or visual appearances. Generally, the bag-of-words (BoW) model is popular in image categorization. However, in BoW model, the feature quantization for image representation is also a lossy ... WebMar 1, 2024 · The Fisher kernel: The Fisher kernel proposed by Jaakkola and Haussler provides a generic framework for deriving a kernel from a generative probability model, . To compute such a kernel, the feature vectors are computed through the Fisher scores, which are the gradients of the log-likelihood of the data x with respect to the model parameters ...
