The sparse representation method is widely used in the area of abnormal crowd motion detection to accurately represent the crowd motions with high dimension features. To overcome its lack of training samples and achieve more accurate detection, a double ...
Text detection is important in the retrieval of texts from digital pictures, video databases and webpages. However, it can be very challenging since the text is often embedded in a complex background. In this paper, we propose a classification-based ...
The employed dictionary plays an important role in sparse representation or sparse coding based image reconstruction and classification, while learning dictionaries from the training data has led to state-of-the-art results in image classification ...
