Abstract: Disclosed are a deep learning model optimization method and apparatus for medical image segmentation. A deep learning model optimization method for medical image segmentation includes: (a) initializing a model parameter; (b) updating the model parameter by performing model-agnostic meta learning (MAML) on a model based on sample batch and applying a gradient descent algorithm to a loss function; (c) setting an optimizer parameter as the updated model parameter, performing one-shot meta-learning on the model, and then updating the optimizer parameter by applying the gradient descent algorithm to the loss function; and (d) updating the model parameter by reflecting the updated optimizer parameter.

Abstract: Disclosed are an apparatus and method for outputting digital video data in a display appliance. The digital video data outputting apparatus includes data converting units for converting various kinds of analog video signals into digital video data, an output signal selector for receiving outputs of the data converting units and selecting any one of the received outputs, and an encoding unit for encoding the output of the output signal selector.

Abstract: An apparatus for separating color and luminance signals from a composite video signal in consideration of the existence and degree of a motion of the video image. The apparatus includes an output section, a first filter, a second filter, a third filter, a motion detector, a motion estimator, a color selector and a luminance selector. The color and luminance selectors select and output the color and the luminance signal from the output signals of the filters in accordance with the existence and degree of the motion.
