摘要： There is provided a system for performing image motion compensation. The system comprises a light source configured to provide pulsed illumination to an object, an imaging unit configured to capture a plurality of images of the object including a first image, a second image, and a third image, and a control unit configured to: determine a first motion map indicating an estimated motion between at least a section in the first image and at least the corresponding section in the second image, determine a second motion map indicating an estimated motion between at least the section in the first image and at least a corresponding section in the third image, or an estimated motion between at least the corresponding section in the second image and at least a corresponding section in the third image, and generate an at least partially motion compensated image.

摘要： There is provided a system (100) for performing ambient light image correction. The system comprises a light source (110), an imaging unit (120) configured to capture a plurality of images of an subject at an exposure time shorter than the wave period of the pulsed illumination, where the pulse frequency of the illumination is not a multiple integral of the frame rate at which the plurality of images are captured, and a control unit (130) configured to: obtain a predetermined number of candidate images, generate a sorted list of pixels by sorting respective pixels each corresponding to a pixel location in the plurality of candidate images, apply a set of weights to the respective sorted list of pixels, and generate an estimated ambient light corrected image based on the plurality of weighted and sorted lists of pixels by summing the plurality of weighted and sorted lists of pixels.

摘要： There is provided a system (100) for performing image motion compensation. The system comprises a light source (110), an imaging unit (120), and a control unit (130). The light source is configured to provide multiplexed illumination to an object in a plurality of color channels, the imaging unit is configured to capture a first image and a second image of the object in the plurality of color channels, and the control unit is configured to determine an estimated motion of pixels between the first image and the second image in a first color channel, and to generate a first motion compensated image by extrapolating the estimated motion of pixels between the first image and the second image to at least another one of the plurality of color channels.

摘要： There is provided an apparatus (100) comprising one or more processors (102) configured to acquire a multi-/hyperspectral two-dimensional image of an object at respective wavelengths. For at least one pixel of the image corresponding to a first point on an object surface, a set of intensity values for said at least one pixel is compared to a characteristic curve to determine a similarity measure. A first angle of the first point is estimated from the similarity measure or a correction is applied to the image at the first point using the similarity measure. The characteristic curve is a difference between a spectrum of at least one second point on the object surface at a second angle with respect to a plane of the image and a spectrum of at least one third point on the object surface at a third angle with respect to the plane of the image.
