Abstract: A computed tomography (CT) image processing apparatus includes an image processor which sets two or more CT number ranges of interest defined by a window level and a window width for CT numbers of CT image data, and maps the CT numbers to display grayscale values of a display. The display displays the CT image data according to a mapping result. A gradient of a graph showing a relationship between the CT numbers and the display grayscale values in a CT number range included in the two or more CT number ranges of interest, is greater than a gradient in a CT number range not included in the two or more CT number ranges of interest. The graph has a zero or positive gradient over an entire section, or has a zero or negative gradient over the entire section.

Abstract: An electronic device is provided. The electronic device includes a sensor module configured to detect an object positioned near the electronic device, a display, a memory storing instructions, and a processor electrically coupled with the sensor module, the display, and the memory. The processor, when executing the instructions, is configured to control the display to display first information guiding a portion of a user's body positioned near the electronic device to maintain a first posture, to acquire a first sensing value by using the sensor module while the first posture is maintained, to control the display to display second information guiding an object to be positioned on one point of the portion of the user's body, to acquire a second sensing value for the object by using the sensor module while the object is positioned on the one point, and to determine a first correction value by using the first sensing value and the second sensing value.

Abstract: A method of recognizing a user's dynamic organ for use in an electric-using apparatus includes comparing a background image and a target image, which are inputted through an imaging element, to detect a candidate region including portions of the target image that are different between the background image and the target image; scanning the candidate region using a window; generating a HOG (histograms of oriented gradients) descriptor of a region of the target image that is scanned when it is judged that the scanned region includes a dynamic organ; measuring a resemblance value between the HOG descriptor of the scanned region and a HOG descriptor of a query template for a gesture of the dynamic organ; and judging that the scanned region includes the gesture of the dynamic organ when the resemblance value meets a predetermined condition.
