Abstract
According to an aspect, there is provided a method for aligning image frames in a sequence of image frames of a subject. The method comprises controlling () one or more light sources to emit multi-spectral light to illuminate the subject, wherein the multi-spectral light comprises at least a first light component having a first illumination wavelength, and a second light component having a second illumination wavelength; controlling () a multi-channel imaging device to obtain two or more sequences of image frames of the subject, wherein each sequence of image frames is obtained using a respective light detection channel of the multi-channel imaging device, wherein the multi-channel imaging device comprises a first light detection channel that is responsive to light in a first spectral band to generate a first sequence of frames of the subject, and a second light detection channel that is responsive to light in a second spectral band to generate respective a second sequence of frames of the subject, wherein the first illumination wavelength is within the first spectral band, and the second illumination wavelength is within the second spectral band; processing () the first sequence of frames to calculate motion vectors for each frame, wherein each motion vector represents a movement of the subject between frames in the first sequence; and aligning () the frames in the second sequence of frames according to the corresponding determined motion vectors such that the subject is aligned across the frames in the second sequence of frames.
