Characteristic data compression device, multi-directional human face detection system and detection method thereof

Abstract

The invention discloses a characteristic data compression device, a multi-directional human face detection system and a detection method of the multi-directional human face detection system. The characteristic data compression device comprises a mirror reflection unit and a transposition unit. The mirror reflection unit is used for comparing a plurality of characteristic values to calculate to obtain mutually-symmetrical characteristic values, and getting rid of one of the two mutually-symmetrical characteristic values in the plurality of characteristic values to form first mirror reflection data. Or calculation is carried out to obtain a position of the characteristic value with the highest specific gravity value to form second mirror reflection data. The transposition unit is used for transposing at least one plate to an angle according to a transposition form to calculate to obtain transposition data.

Description

technical field [0001] The present invention relates to a face feature data compression device, in particular to a feature data compression device that utilizes the mirrorability and transposition of face feature data to perform data compression, and applies the feature data compression A multi-directional face detection system and a detection method of a device. Background technique [0002] The current face detection method is to input multiple images to be tested into a learning model. The learning model learns how to distinguish whether the image to be tested contains the preset template feature according to the preset template feature. Whether it is an active learning architecture such as: Neural Network (Neural Network), expert system, fuzzy system (Fuzzy) or a classification learning architecture such as: Support Vector Machine (Support Vector Machine, SVM), principal axis component analysis (Principal Components Analysis, PCA), Snow method or Boosting method all ne...
