Pictures are the most effective means of conveying information. A picture is worth a thousand words. Pictures concisely convey information about positions, sizes and interrelationships between objects. Human beings are good at deriving information from such images, because of our innate visual and mental abilities. About 75% of the information received by human is in pictorial form. The paper d...

Typhoon inflicts terrible damage due to thunderstorms, violent winds, torrential rain, flooding and extreme high tides. Improving the early typhoon forecast capability is important for the disaster prevention. In recent years, many scholars have made efforts in typhoon center location, typhoon intensity estimation and moving path prediction from the satellite images. Moreover, it may be useful ...

Satellite images are being used in numerous fields of aspects. The major controversy of various types of images is their resolution. In this paper, proposed a new satellite image resolution enhancement technique based on the interpolation of the high frequency sub bands obtained by discrete wavelet transform and the input image. The proposed declaration intensification technique uses DWT to dec...

Satellite images are being used in many fields of research. One of the major issues of these types of images is their resolution. In this paper, we propose a new satellite image resolution enhancement technique based on the interpolation of the high-frequency subbands obtained by discrete wavelet transform(DWT) and the input image. The proposed resolution enhancement technique uses DWT to decom...

Image quality is important for taking full advantage of satellite data. As a common indicator, the National Imagery Interpretability Scale (NIIRS) is widely used for image quality assessment and provides a comprehensive representation of image quality from the perspective of interpretability. The ZY-3 (Ziyuan-3) satellite is the first civil high resolution mapping satellite in China, which was ...

We present an approach for tracking water courses in satellite images, a general strategy for tracking and recognising features in computer vision tasks on satellite images. Our approach is related to recent work in automatic image interpretation and urban scene analysis. We report a method for image recognition from multi-spectral SPOT satellite imagery, based on the different response of wate...
