Abstract:
The present invention relates to a surveillance system having a method for tampering detection and correction. The surveillance system is able to detect tampering of the camera view and thereon, adjust its video analytics configuration parameters to perform video analytics even though the orientation of the camera (10) has been changed as long as a partial of the ROI is within the tampered camera view. The surveillance system comprises of at least one camera (10), a video acquisition module (20), a storage device (30), an image processing module (40), a display module (50) and a post detection module (60).
Abstract:
The present invention discloses a system and method for object tracking and image projection which may be used for a surveillance system or for providing information to users by way of a display adjacent to users within the monitored area. The system comprises a video camera (200), a light projector (208), housing for the light projector (210), a plurality of motors (202, 204, 206) for providing movements to the light projector (208), a support pole (216), and a mirror (212) for enabling the light projector (208) to illuminate or project images at the targeted object for tracking by way of reflecting therefore diverting the illumination from the light projector (208). There is further provided a control and processing system (300) connected to the projector (208) and the camera (200) for providing overall system control and further processing of the captured images by the camera (200). The system of the present invention provides continuous tracking of an object within the monitored area upon suitably prompted by the control and processing system (300).
Abstract:
A surveillance method for the automatic detection of unattended object or removal of a stationary object via a surveillance image analysis. The method is operative in analyzing image data received from surveillance cameras and providing in real time a set of alarm messages to security personnel. The invention is useful for detecting unattended objects or removal of stationary objects.
Abstract:
The present invention relates to a method for estimating a possible route of an incomplete tag access information. The method comprises the steps of receiving all tag access information including tag identification numbers, connected region identification and need tag values; creating a region ontology for each tag access information received; setting the row and column of the region ontology according to the connected region identification; filling up the region ontology with tag identification numbers and need tag values; generating intensity profile data based on historical data; searching for probable route based on the region ontology; estimating the best route based on the probable route found and intensity profile data; and displaying the best route.
Abstract:
The present invention provides a method for processing videos captured through a stereo camera, the videos having a plurality of frames, each frames includes at least a left and a right images. The method includes acquiring videos captured by the pair of stereo cameras (101) and acceleration information of the stereo camera (101) detected through the accelerometer (102); extracting feature points in the right and left images of a current frame; matching the feature points between the right and left images, wherein disparity value of each feature point is computed; clustering the feature points on a current frame into one or more clouds based on their appearance and distance; determining a correspondence between the clouds of the current frame and previous frame; classifying the clouds through estimating statistical disparity distribution of each cloud to identify if the respective clouds are new clouds, existing clouds or unknown clouds; and merging the clouds that are determined to be a same object based on the tracking information and changes of disparity of the clouds over time. A system carrying out the above method is also provided herein.
Abstract:
The present invention provides a system and method for processing sequence of image frames captured through an imaging device, the imaging device includes an accelerometer. The system and method comprise an adaptive temporal background subtraction unit and a dynamic foreground object estimation unit for evaluating whether each pixel is either a moving object pixel or a non-moving object pixel based on the classification of the pixels between the first motion map and the second motion map generated thereon.
Abstract:
The present invention provides for an imaging apparatus, which is used in a novel visual processing device, which provides assistance in parking or obstacle avoidance to the vehicle user.
Abstract:
A model to calculate the movement risk probability of an object to deviate from a known standard path and use of the same in a surveillance system.
Abstract:
The invention accordingly provides an apparatus and method for facilitating in estimating the cloud cover within the sky. The observation method is conducted automatically and is able to provide reliable output.
Abstract:
An image scanning device comprising of energy ray sensitive elements (101), lenses (103), a slit collimator (104) and a controller (105) is disclosed. Energy ray sensitive elements (101) refer to photo sensitive materials to capture visible light or thermal sensitive materials to capture infrared, which gives electrical signal corresponding to incident energy ray. The energy ray sensitive elements (101) are arranged in an array and the lenses (103) are arranged in an array and placed in front of the sensitive elements (101). The slit collimator (104) is used to select energy ray column to be acquired at a time. The controller (105) is used to control the motion of the slit collimator (104) from a start position to an end position, to stop at every column and acquire image data of an exposed energy ray sensitive column at a time, whereby the sequence of acquiring columns of images forms a two dimensional image.
