This paper presents an efficient and automatic method for detecting filament disappearances. This method was applied to the Big Bear Solar Observatory's (BBSO) full-disk Hα images. The initial step is to detect the filaments in the solar image, then determine if they are growing, stable or disappearing. If a disappearing filament is found, the solar(More)
– This paper presents one efficient automatic detection method for filament disappearance. The method was applied to the Big Bear Solar Observatory (BBSO) full-disk Hα images. The initial step is to detect the filament pixels by the threshold method. Then, using a region-growing method, we merge the adjacent detected pixels to obtain all filament areas.(More)
