1. Single-value decomposition: an important part of linear algebra, has been widely used in pattern recognition for dimensionality reduction and Information Retrieval Applications. 2. Independent Component Analysis 3. Non-negative matrix decomposition 4. Nonlinear Dimensionality Reduction Algorithm: ① Kernel PCA ② graph-based method (Laplace operator, local linearembedding (LLE), Isometric Mapping (Isomap )) 5. Discrete Fourier Transformation 6.

This chapter focuses on feature generation in image analysis.1. Regional Features: ① texture properties ② local linear transformation extracting texture features ③ moment ④ Parameter Model2. shape and size Features: ① Fourier features ② chain code, which is the most common technique for describing boundary shapes ③ moment-based (moment) features ④ geometric features3, fractals (a glimpse at fractals)Two important tools were introduced into the pattern
