Abstract
A method of spectral-spatial-temporal image detection is disclosed. In one embodiment, a spectrally differenced image is obtained by computing a difference of at least two intensity values in at least two spectral bands of an image. Further, a spatially filtered spectral image is obtained by applying a spatial median filter to the obtained spectrally differenced image. Furthermore, a temporal image is obtained by determining a temporal pixel value difference using a computed predictive frame difference. In addition, a spectral-spatial-temporal filtered image for detection is obtained by using the obtained spatially filtered spectral image and the temporal image.
