一种改进的自然场景特征提取方法
Improved Feature Extraction Method for Natural Scene
摘要
Abstract
Feature extraction method for natural scene has some shortcomings such as large computing costs and low identification accuracy. So this paper proposes an improved extraction method. It combines three-scale gist feature with Histograms of Oriented Gradients(HOG) to describe the scene, and uses support vector machine to realize classification. Experimental result shows that the feature computation is accelerated and the classification accuracy of natural scene image is improved by using the improved method.关键词
