20130343654 | GENERATING A BINARY DESCRIPTOR REPRESENTING AN IMAGE PATCH - Embodiments described herein provide a system and method for generating a binary descriptor representing an image patch ( | 12-26-2013 |
20140208208 | VIDEO NAVIGATION THROUGH OBJECT LOCATION - The present invention relates to a method for navigating in a sequence of images. An image is displayed on a screen. A first object of the displayed image is selected at a first position according to a first input. The first object is moved to a second position according to a second input. At least one image is identified in the sequence of images where the first object is close to the second position. Playback of the sequence of images is started beginning at one of the identified images. | 07-24-2014 |
20150015792 | FILTERING A DISPLACEMENT FIELD BETWEEN VIDEO FRAMES - The invention relates to a method for filtering a displacement field between a first image and a second image, a displacement field comprising for each pixel of the first (reference) image a displacement vector to the second image (current). The method comprises a first step of spatio-temporal filtering wherein a weighted sum of neighboring displacement vectors produces, for each pixel of the first image, a filtered displacement vector. The filtering step is remarkable in that a weight in the weighted sum is a trajectory weight, that is a trajectory weight is representative of a trajectory similarity. According to an advantageous characteristic, a trajectory associated to a pixel of the first image comprises a plurality of displacement vectors from the pixel to a plurality of images. According to another advantageous characteristic, a trajectory weight comprises a distance between a trajectory from the pixel and a trajectory from a neighboring pixel. The method also relates to a graphics processing unit and to computer-readable medium for implementing the weight filtering method. | 01-15-2015 |
20150127648 | IMAGE DESCRIPTOR FOR MEDIA CONTENT - A method for generating image descriptors for media content of images represented by a set of key-points, fn, is recommended which determines for each key-point of the image, designated as a central key-point, a neighbourhood of other key-points, fml, whose features are expressed relative to those of the central key-point. A sparse photo-geometric descriptor, SPGD, of each key-point in the image being a representation of the geometry and intensity content of a feature and its neighbourhood is provided to perform an efficient image querying for efficient searches. The approach demonstrates that incorporating geometrical constraints in image registration applications does not need to be a computationally demanding operation carried out to refine a query response short-list. | 05-07-2015 |
20150178387 | METHOD AND SYSTEM OF AUDIO RETRIEVAL AND SOURCE SEPARATION - A method and a system of audio retrieval and source separation are described. The method comprises the steps of: receiving a textual query; retrieving a preliminary audio sample from an auxiliary audio database; retrieving a target audio sample from a target audio database; and separating the retrieved target audio sample into a plurality of audio source signals. The corresponding system comprises an input unit, a storing unit and a processing unit to implement the method. | 06-25-2015 |
20150179228 | SYNCHRONIZED MOVIE SUMMARY - The present invention relates to a method for providing a summary of an audiovisual object. The method comprises the steps of: capturing information from the audiovisual object; identifying the audiovisual object; determining the time index of the captured information relative to the audiovisual object; and providing a summary of a portion of the identified audiovisual object, the portion being comprised between the beginning and the determined time index of the identified audiovisual object. | 06-25-2015 |
20150339828 | SEGMENTATION OF A FOREGROUND OBJECT IN A 3D SCENE - A method and a module for segmenting a foreground region from a background region in a 3D scene captured by n capturing devices. A reduced number of 3D samples are selected in the scene. These 3D samples are projected in each captured image. Foreground probability and background probabilities are computed for each selected 3D sample based on color models and the projection of these samples in the images These probabilities are used to update the color models. These probabilities are then re-computed based on the updated color models. These steps are reiterated until the color models or the foreground and background probabilities of the selected 3D samples converge. A final segmentation is computed using foreground color models and foreground and background probabilities. | 11-26-2015 |
