Pansharpening algorithms have been widely discussed since the poor spatial resolution of the hyperspectral images limits their use in identifying textures or some other detailed information of different ground types in many applications such as sophisticated interpretation. To overcome the defect is of the top priority in this topic, for the conventional pansharpening methodologies usually suffer...
In this paper, We propose a method to recognize the pointer barometer reading in transformer substations by image processing technology automatically. The method contains two steps. First, we use segmentation and morphology to extract the dial from the background. Second, we use improved Hough Transform method to locate the pointer. With the initial range information, we can recognize the real reading...
