Abstract: A computer readable medium and an image processing method implemented by a computer processor, for determining a color value for a given pixel of a current frame. The method comprises: selecting, by the computer processor, coordinates of a sample position within the given pixel of the current frame; determining, by the computer processor, a present color value for said sample position coordinates; blending, by the computer processor, the computed color value with a color value for at least one pixel of a previous frame, the at least one pixel of the previous frame including a pixel related to the given pixel; and storing in a memory the blended color value for the given pixel of the frame. Thus, aliasing may be mitigated by dynamically varying the relative contributions of the past and the present to the rendered color value of pixels in a frame.

Abstract: A method for selecting clothing includes a computer that processes markings and produces a three-dimensional mathematical model of the body of a subject, which is input into a database using an identification number pertaining to the same. The database is accessible by the buyer, the seller and the clothing manufacturer. The method is applicable for selecting clothing for humans, and also for animals. Standard-shape graphical elements are applied, in a regular pattern, to an elastic covering which is worn on the body, and the relationship between the elements is used as a basis for forming a three-dimensional model of the body. Models of clothing, which correspond to the parameters of the three-dimensional model of the subject, are selected from clothing databases. A consumer receives, on the screen of their computer, three-dimensional images of their body in the selected clothing models.

Abstract: A head mounted display (HMD) adjusts feature tracking parameters based on a power mode of the HMD. Examples of feature tracking parameters that can be adjusted include the number of features identified from captured images, the scale of features identified from captured images, the number of images employed for feature tracking, and the like. By adjusting its feature tracking parameters based on its power mode, the HMD can initiate the feature tracking process in low-power modes and thereby shorted the time for high-fidelity feature tracking when a user initiates a VR or AR experience at the HMD.

Abstract: A technique for rendering virtual content to a user stores map data of features in a physical environment of the user and measures the location of the user with stationary sensors placed at respective locations within the environment. A server provides the location of the user and portions of the map data to a headset worn by the user. The headset is thus enabled to render virtual content at apparent locations that are based on the measured location of the user and the features described by the map data.

Abstract: Dynamic spread anti-aliasing is described. In some embodiments, a filled object is segmented into control tiles. Along the object border, multiple exterior control tiles respectively correspond to multiple curves forming the border. For each curve, one side is filled and the other is anti-aliased to smooth the appearance of the filled object. Each exterior control tile is expanded to create an expanded control tile having a spread zone that includes additional pixels. For example, a control triangle is transformed into a control rectangle, and the control rectangle is enlarged to create an expanded control rectangle by extending an edge outward and away from the curve on the side to be anti-aliased. The additional pixels of the spread zone are subjected to anti-aliasing, such as by applying alpha modulation to the pixels based on respective distances between the pixels and the curve. For subpixel zoom levels, pixel color can be adjusted.

Abstract: Indication systems for the drivers of vehicles and cars include a data display device that combines two optical systems of the image display—the virtual image display system and the real image display system.

Image quality and safe driving may be improved due to the combination of two systems and control of the level of detail of displayed data.

Abstract: An ultrasound system and method are described for acquiring standard views of the fetal heart simultaneously with real-time imaging. A matrix array probe is manipulated until a first standard view such as a 4-chamber view is acquired. The first standard view image is matched to its corresponding plane in a fetal heart model. From the matched plane of the heart model, the orientations of the other standard views are known from the geometrical relationships of structures within the heart model. This orientation information is used to control the matrix array probe to automatically scan the planes of all of the standard views simultaneously in real-time.
