Abstract: A method of medical image registration is to be implemented by a computer device, and includes steps of: obtaining an ultrasound target image corresponding to an area of interest in an ultrasound image; for each of multiple computed tomography (CT) images, obtaining a CT candidate image that corresponds to an area of interest in the CT image; for each of the CT candidate images, calculating a similarity between the CT candidate image and the ultrasound target image; making one of the CT candidate images that corresponds to the greatest similarity among the CT candidate images serve as a CT target image; and performing image registration on the ultrasound target image and the CT target image.

Abstract: A method for correcting a dehazed medical image is proposed to include: acquiring first saturation values of a medical image and second saturation values of a dehazed medical image in an HSV color space; acquiring a saturation difference value based on the first saturation values and the second saturation values; acquiring a correction value based on the medical image and a threshold value; acquiring a saturation correction value based on the saturation difference value and the correction value; and correcting the dehazed medical image based on the saturation correction value.

Abstract: An endoscopic system includes a mechanical arm, an endoscope and a control unit. The endoscope is held by the mechanical arm, and is configured to capture an image. The control unit is electrically connected to the mechanical arm and the endoscope, and is configured to receive and process the image captured by the endoscope, to determine whether the image has at least two specific instruments that are arranged in a specific configuration, and to drive the mechanical arm to move the endoscope when the determination is affirmative.
