20090103808 | CORRECTION OF DISTORTION IN CAPTURED IMAGES - An image processing method comprises analysing an image of a portion of text, and detecting the inter-line spacing and the inter-word spacing across the area of the image. Based on the inter-line and inter-word spacings, a quadrilateral shape is derived which represents the deformation of the text image from an undistorted image. The image is modified to perform perspective correction based on the derived quadrilateral. | 04-23-2009 |
20110102318 | USER INPUT BY POINTING - Presented is apparatus for capturing user input by pointing at a surface using pointing means. The apparatus comprises: a range camera for producing a depth-image of the pointing means; and a processor. The processor is adapted to determine from the depth-image the position and orientation of a pointing axis of the pointing means; extrapolate from the position and orientation the point of intersection of the axis with the surface; and control an operation based on the location of the point of intersection. | 05-05-2011 |
20110131534 | SYSTEM AND METHOD FOR DYNAMICALLY DISPLAYING STRUCTURALLY DISSIMILAR THUMBNAIL IMAGES OF AN ELECTRONIC DOCUMENT - A system and method for dynamically displaying structurally dissimilar thumbnail images generated from multiple pages of an electronic document based on a display size of a display device is disclosed. In one embodiment, one or more candidate images are selected based on a generated metric for dissimilarity for each one of multiple images associated with multiple pages of an electronic document, where the metric for dissimilarity for each one of the multiple images is generated by comparing each image of the multiple images with substantially previous images of the multiple images. Then, the selected one or more candidate images are dynamically displayed as structurally dissimilar thumbnail images based on a display size of a display device. | 06-02-2011 |
20110219340 | SYSTEM AND METHOD FOR POINT, SELECT AND TRANSFER HAND GESTURE BASED USER INTERFACE - A system and method for a point, select and transfer hand gesture based user interface is disclosed. In one embodiment, a depth image of a hand gesture is captured using an in-front camera substantially on a frame by frame basis within a predefined interaction volume. Also, a nearest point of the hand gesture to a display screen of a display device is found using a substantially nearest depth value in the captured depth image for each frame. Further, an image-to-screen mapping of the captured depth image and the found nearest point to the display screen is performed upon validating the found nearest point as associated with the hand for each frame. Moreover, one of select options displayed on the display screen is pointed and selected when the substantially nearest depth value is within one or more predetermined threshold ranges, and based on the outcome of the image-to-screen mapping. | 09-08-2011 |
20110234492 | Gesture processing - Presented is method and system for processing a gesture performed by a user of an input device. The method comprises detecting the gesture and determining a distance of the input device from a predetermined location. A user command is then determined based on the detected gesture and the determined distance. | 09-29-2011 |
20120056901 | SYSTEM AND METHOD FOR ADAPTIVE CONTENT SUMMARIZATION - System and method for adaptive content summarization is disclosed. In one embodiment, a summary size of content is computed based on a usability cost function and an information loss function. Further, a summary of the content is extracted based on the summary size. Furthermore, the extracted summary is displayed on a display device. | 03-08-2012 |
20120093360 | HAND GESTURE RECOGNITION - Systems, methods, and machine readable and executable instructions are provided for hand gesture recognition. A method for hand gesture recognition can include detecting, with an image input device in communication with a computing device, movement of an object. A hand pose associated with the moving object is recognized and a response corresponding to the hand pose is initiated. | 04-19-2012 |
20120119984 | HAND POSE RECOGNITION - Hand pose recognition comprises determining an initial hand pose estimate for a captured input hand pose and performing iterations based upon hand pose estimates and residues between such estimates and hand pose estimates. One or more control signals are generated based upon the hand pose recognition. | 05-17-2012 |
20120197991 | METHOD AND SYSTEM FOR INTUITIVE INTERACTION OVER A NETWORK - Intuitive interaction may be performed over a network. The interaction may include collection of feedback from participants, wherein the feedback is active, passive, or a combination of both. The feedback from the participants may be aggregated and the aggregated feedback can be provided to at least one participant or a non-participant. | 08-02-2012 |
20120278729 | METHOD OF ASSIGNING USER INTERACTION CONTROLS - Provided is a method of assigning user interaction controls. The method assigns, in a scenario where multiple co-present users are simultaneously providing user inputs to a computing device, a first level of user interaction controls related to an object on the computing device to a single user and a second level of user interaction controls related to the object to all co-present simultaneous users of the computing device. | 11-01-2012 |
20130268476 | METHOD AND SYSTEM FOR CLASSIFICATION OF MOVING OBJECTS AND USER AUTHORING OF NEW OBJECT CLASSES - A system and method for classification of moving objects and user authoring of new object classes is disclosed. In one embodiment, in a method of classification of moving objects, a moving object is inputted. Then, an object descriptor and a motion descriptor are extracted from the inputted moving object. Multiple initial candidate library object descriptors are identified from an object library and a motion library using the extracted object descriptor and the extracted motion descriptor. An initial object class estimate is identified based on the identified multiple initial candidate library object descriptors. Then, an initial residue is computed based on the extracted object descriptor and the identified multiple initial candidate library object descriptors associated with the initial object class estimate. The object class estimates are iteratively identified and it is determined whether the object class estimates converge based on a stopping criterion. | 10-10-2013 |
20130343611 | Gestural interaction identification - A method of identifying gestural interaction comprises detecting a user with an imaging device, detecting with the imaging device the depth value at the centroid of the user with respect to the imaging device, detecting with the imaging device the closest distance of the user with respect to the imaging device, and, with a processor, identifying the initiation of a gestural interaction based on the ratio of the closest distance and the depth value at the centroid of the user is above a predetermined threshold. A computer program product for identifying initiation and termination of gestural interaction within a gestural interaction system comprises a computer readable storage medium having computer usable program code embodied therewith, the computer usable program code comprising computer usable program code that identifies the initiation of a gestural interaction by a user depending on whether a virtual bubble around the user has been broken. | 12-26-2013 |
