We present a multi-channel segmentation scheme to identify different features of the solar corona, such as coronal holes, active regions and the quiet sun (especially in the ultraviolet and extreme ultraviolet images). In contrast to common techniques, we use an approach that uses image intensity and relative contribution of each of the wavelengths. This(More)
Solar images taken at different wavelengths enable scientists to visualize and analyze the suns activities. The Solar Dynamics Observatory (SDO) provides high-resolution images of the sun, with cadence in seconds, taken at varying wavelengths, resulting in finely detailed, almost continuous data for researcher's examination. We propose an approach to find(More)
