英文摘要	we present a framework for image classification that extends beyond the window sampling of fixed spatial pyramids and is supported by a new learning algorithm. based on the observation that fixed spatial pyramids sample a rather limited subset of the possible image windows, we propose a method that accounts for a comprehensive set of windows densely sampled over location, size, and aspect ratio. a concise high-level image feature is derived to effectively deal with this large set of windows, and this higher level of abstraction offers both efficient handling of the dense samples and reduced sensitivity to misalignment. in addition to dense window sampling, we introduce generalized adaptive l(p)-norm multiple kernel learning (ga-mkl) to learn a robust classifier based on multiple base kernels constructed from the new image features and multiple sets of prelearned classifiers from other classes. with ga-mkl, multiple levels of image features are effectively fused, and information is shared among different classifiers. extensive evaluation on benchmark datasets for object recognition (caltech256 and caltech101) and scene recognition (15scenes) demonstrate that the proposed method outperforms the state-of-the-art under a broad range of settings.
