Abstract: The invention provides methods of detecting and describing features from an intensity image. In one of several aspects, the method comprises the steps of providing an intensity image captured by a capturing device, providing a method for determining a depth of at least one element in the intensity image, in a feature detection process detecting at least one feature in the intensity image, wherein the feature detection is performed by processing image intensity information of the intensity image at a scale which depends on the depth of at least one element in the intensity image, and providing a feature descriptor of the at least one detected feature. For example, the feature descriptor contains at least one first parameter based on information provided by the intensity image and at least one second parameter which is indicative of the scale.

Abstract: There is disclosed a method and mobile device for displaying points of interest in a view of a real environment displayed on a screen of the mobile device with a functionality for interaction with a user, which comprises the steps of: capturing an image of the real environment or a part of the real environment using a camera, determining at least one point of interest related to the real environment, determining an image position of the at least one point of interest in the image, displaying at least part of the image on at least part of the screen, overlaying a computer-generated indicator with the at least part of the image on the screen at a screen position according to the image position of the at least one point of interest, displaying a computer-generated virtual object related to the at least one point of interest on the screen at a screen position determined according to the screen position of the computer-generated indicator and which is adjacent to a bottom edge of the screen, displaying a visually perceivable relation indication indicative of a relation between the computer-generated virtual object and the computer-generated indicator. The mobile device may perform an action related to the at least one point of interest if at least part of the computer-generated virtual object displayed on the screen is touched.
