In image compression and image processing applications, region of interest (ROI) of images are hoped to get better compression results compares with region of back ground. Combining the advantages of general scaling based method (SBM) for the processing region of interest in JPEG2000, a novel ROI image coding method using multiwavelet-based set partitioning(More)
In the past decade, with the development of kernel-based machine learning, many different multiple kernel learning (MKL) methods were proposed which focus on selecting the pivotal kernel to be preserved and confirming the optimal kernel combination. In this paper, we address the question mentioned above by using subspace projection method and put forward a(More)
The projection errors caused by curvature of the earth and relief are two important problems in geometric correction, especially in the case of imaging with large view angles. General polynomial correction model is only effective to flat area and ineffective to correct projection errors caused by both curvature of the earth and relief. According to the(More)
