The moving picture encoding apparatus includes: a mode selector for selecting and outputting a prediction mode; a predictor for predicting pixel values of pixels to be encoded of an input video based on the prediction mode to thereby output a residue signal block; a transform/quantization unit for performing DCT onto the residue signal block and quantizing the transformed residue signal block; and an encoder for adaptively scanning and encoding the quantized residue signal block based on the prediction mode.

Abstract: A regularized multi-metric active learning (AL) image classification system which includes three main parts. First, a regularized multi-metric learning process is utilized to jointly learn distinct metrics for different types of image features from remotely sensed image data. The regularizer incorporates the unlabeled data based on the neighborhood relationship, which helps avoid overfitting at early stages of AL, when the quantity of training data is particularly small. Then, as AL proceeds, the regularizer is also updated through similarity propagation, thus taking advantage of informative labeled samples. Finally, multiple features are projected into a common feature space, in which a batch-mode AL strategy combining uncertainty and diversity is utilized in conjunction with k-nearest neighbor (kNN) classification to enrich the set of labeled samples.
