Abstract: A method of detecting moving objects, including the following steps: extracting first and second images from a video of an observed space; detecting corner points in the images; using the points, extracting a feature vector; identifying corresponding points in the images; determining a homography to perform image registration between the images; applying a warping of the second image based on the homography to obtain a warped second image; calculating a difference in individual pixels between the warped second image and the first image to identify pixels that differ; obtaining a third image by comparing the second warped image against the first image; identifying a bounding box in the third image for each group of adjacent pixels; calculate the optical flow based on the first image and the warped second image; extracting from the optical flow a matrix corresponding to the magnitude of the optical flow.
Abstract: A method for the recognition of real objects, in particular three-dimensional objects, for augmented reality engines comprises the steps of: producing at least one three-dimensional drawing of the real object; defining at least one characteristic measurement of the real object starting from the three-dimensional drawing; entering in an electronic device said at least one characteristic measurement of the real object; positioning the electronic device in such a way as to view the real object; detecting an image of the real object in the electronic device; superposing said at least one characteristic measurement of the real object on the image detected; aligning said at least one characteristic measurement of the real object with the image detected in such a way as to determine the positioning of the electronic device relative to the real object.
Abstract: An automatic monitoring system and a method for automatically monitoring the presence of any birds in a space or area using artificial vision techniques. That system and method also allow automatic detection of the species to which such birds belong, their movements, for example the flight trajectories, relative to the observation space or area, as well as the number of such birds.
