The method is based on the edge density distribution of the image. In the preprocessing stage a face is approximated to an ellipse, and a genetic algorithm is applied to search for the best ellipse region match. In the feature extraction stage, the genetic algorithm is applied to extract the facial features, such as the eyes, nose and mouth, in the predefined sub regions. The simulation results validates that the proposed method is capable of automatically extracting features from various video images effectively under natural lighting environments and in the presence of certain amount of artificial noise and of multi-face oriented with angles.","PeriodicalId":184547,"journal":{"name":"Proceedings of the 2002 Congress on Evolutionary Computation.

Satisfactory results and significant speedup can be achieved by aSAIGA, as shown by simulation.","PeriodicalId":184547,"journal":{"name":"Proceedings of the 2002 Congress on Evolutionary Computation.

Adaptive denoising in spectral analysis by genetic programming 基于遗传规划的谱分析自适应去噪
J. Rowland, Janet Taylor
{"title":"Adaptive denoising in spectral analysis by genetic programming","authors":"J. Rowland, Janet Taylor","doi":"10.1109/CEC.2002.1006222","DOIUrl":"https://doi.org/10.1109/CEC.2002.1006222","url":null,"abstract":"This paper relates to supervised interpretation of the infrared analytical spectra of complex biological samples. The aim is to produce a model that can predict the value of a measurand of interest, such as the concentration of a particular chemical constituent in complex biological material. Conventionally, a number of spectra are co-added to reduce measurement noise and this is time consuming. In this paper we demonstrate the ability of evolutionary search to provide adaptive averaging of spectral regions to provide selective tradeoff between spectral resolution and signal-to-noise ratio. The resultant denoised subset of the variables is then input to a proprietary Genetic Programming (GP) package which forms a predictive model that compares well in predictive power with a combination of Partial Least Squares Regression (PLS) and adaptive denoising. This demonstrates the considerable advantage that, given appropriate node functions, the GP could handle the entire process of denoising and forming the final predictive model all in one stage. This reduces or removes the need for co-adding with a consequent reduction in data acquisition time.","PeriodicalId":184547,"journal":{"name":"Proceedings of the 2002 Congress on Evolutionary Computation.
