Abstract: A method for color restoration in images includes accessing an image of an object and processing the image based on an image processing operation to provide a processed image, where the image processing affects color of the object. The method further includes determining color adjustment parameters using a trained neural network, wherein an input to the trained neural network is based on the image and the processed image, restoring color in the processed image based on the color adjustment parameters to produce a color-restored image, and displaying the color-restored image on a display device.

Abstract: A sheath for covering an endoscope includes a latch assembly, an elongate body extending distally from the latch assembly, and a sheath tip extending distally from the elongate body. The latch assembly includes a main housing and a guide housing, the guide housing movable relative to the main housing to increase a longitudinal length of the latch assembly. The sheath tip has a front face including first and second windows disposed within respective first and second openings defined in the front face. The first and second windows are configured to correspond with respective lighting and imaging windows of an endoscope.

Abstract: A method for smoke reduction in images includes accessing an RGB image of an object obscured by smoke, determining a dark channel matrix of the RGB image, estimating an atmospheric light matrix for the RGB image based on the dark channel, determining a transmission map based on to the atmospheric light matrix and the dark channel matrix, de-hazing the RGB image based on the transmission map to reduce the smoke in the RGB image, and displaying the de-hazed RGB image on a display device. The RGB image includes a plurality of pixels. The dark channel matrix includes, for each pixel of the plurality of pixels, a minimum color component intensity for a respective pixel area centered at the respective pixel. The atmospheric light matrix includes an atmospheric light component value for each of the plurality of pixels.

Abstract: Systems and methods for haze reduction in images are disclosed. An exemplary method for haze reduction includes accessing an image of an object obscured by haze where the image has an original resolution, downscaling the image to provide a downscaled image having a lower resolution than the original resolution, processing the downscaled image to generate dehazing parameters corresponding to the lower resolution, converting the dehazing parameters corresponding to the lower resolution to second dehazing parameters corresponding to the original resolution, and dehazing the image based on the second dehazing parameters corresponding to the original resolution.
