Oil spill detection becomes very important nowadays, due to the importance of oil and to prevent pollution caused by oil leakage. Synthetic Aperture Radar (SAR) images show oil spill boundaries clearly. An oil spill appears as an obscure spot in SAR images. Therefore, thresholding is considered the best method to extract this patch and define its boundaries clearly. This paper proposes a novel thresholding...
We propose a shape-adaptive wavelet-based finite ridgelet coding method, which can efficiently code an arbitrarily shaped video object. Mechanism of SA-FRIT on the shape adaptive ridgelet transform are discussed, based on the mask images on video object shape adaptive ridgelet three level decomposition. The existing SPIHT was improved, compression method proposed an extension of SPIHT. The method...
