This document discusses the process of extracting local features from images and how these features are used in various applications such as object recognition and image classification. We explore techniques for building a local feature dictionary, utilizing occurrence histograms to represent the distribution of features. The approach aims to improve the robustness and accuracy of image analysis by capturing distinctive local patterns while minimizing noise. This work highlights the importance of local feature dictionaries in enhancing machine learning models for image processing tasks.
