Abstract: An apparatus for estimating a malignant tumor includes: a segmentor configured to segment a first medical image of an object into a first ROI including a mass and a second medical image of the object into a second ROI including a mass; an interest region determiner configured to acquire a first matched ROI and a second matched ROI, which is matched to the first matched ROI based on location information of the first ROI and the second ROI, respectively; a feature extractor configured to extract a similar feature indicating a degree of similarity between the first matched ROI and the second matched ROI, from the first matched ROI and the second matched ROI; and a classifier configured to generate malignant tumor information indicating whether the mass included in the first matched ROI and the second matched ROI is the malignant tumor, based on the extracted similar feature.

Abstract: An image obtaining apparatus, for obtaining an image from an image sensor provided in a vehicle, is provided. The image obtaining apparatus includes: a processor, and a memory including at least one instruction executable by the processor. In response to the at least one instruction being executed by the processor, the processor is configured to: obtain an initial image from the image sensor, the initial image including an object; determine a type of the object included in the initial image; adjust a shutter speed of the image sensor based on the determined type of the object included in the initial image; and obtain a first image from the image sensor based on the adjusted shutter speed.

Abstract: A method and apparatus for controlling a vision sensor are provided. The apparatus and corresponding method are configured to predict an expected point, on a traveling path of a host vehicle, at which an illumination variation greater than or equal to a threshold is expected to occur, and determine whether the host vehicle is located within a threshold distance. The apparatus and corresponding method are also configured to control a vision sensor in the host vehicle based on the expected illumination variation in response to the host vehicle being located within the threshold distance.
