Abstract: Systems and techniques for noise reduction in video are described. Example implementations provide improved motion-adaptive temporal or spatio-temporal noise reduction that use an improved blending of the current frame with previous frames. The improved blending may be particularly effective for processing video captured in noisy environments such as low-light and/or mobile environments. In some example implementations, the improved blending is based on more accurately distinguishing between pixel difference in adjacent images that are caused by motion rather than noise.

Abstract: A gate driver circuit, a display panel, and a display device. A number of emission start signals, with at least one a delay time, a pulse width, or a combination thereof, are supplied in a frame period in which display driving is performed at a low driving frequency. This decreases a degree by which luminance appearing in the frame period is reduced, or changes characteristics of frequency components of luminance, thereby preventing flicker from being observed. The display driving is performed at the low driving frequency reduces power consumption, and is performed at a lower driving frequency to improve the efficiency of the display device.

Abstract: A method and an apparatus for reducing electromagnetic waves in a mobile device are provided. According to the method, in a mobile device having the first and second modules with different functions, the apparatus operates the first module at the first operating frequency. If there is a request for operating the second module while the first module is operated, the apparatus changes the first operating frequency to a second operating frequency which is different from the first operating frequency, and operates the first module at the second operating frequency. The apparatus reduces a total magnitude of electromagnetic waves caused by a simultaneous operation of two or more modules, thereby enhancing the quality of the mobile device and minimizing any undesirable impact upon the human body.

Abstract: A system and method are provided for model-based coronary artery calcium (CAC) scoring. A model image of a heart region is aligned with an image of a patient's heart region in order to more easily identify the coronary arteries and other relevant anatomical features in the image. Once the images are aligned, relevant calcium plaques are identified by their presence within a coronary artery, and the relevant plaques are then labeled by the specific coronary artery in which they are located. The coronary arteries with the labeled plaques are scored individually based on their size and X-ray attenuation, and an overall score based on all of the relevant plaques is then computed, which is related to the patient's risk for coronary artery disease.
