Abstract: An identity-concealing motion detecting and portraying device, for privacy-preserving monitoring or surveillance, concealing the identity of detected moving subjects and their observed location and denying access to original video frames. The device includes a video camera that collects video frame images of an area; a volatile memory storing a video buffer, the video camera storing a stream of video frames in the buffer. A processor, for each pair of successive video frames in the video buffer, computes a simple difference frame of the pair; erases the first video frame of the pair from the volatile memory; and outputs the difference frames as portrayed motion video. The device may comprise an analytics module for detecting specific events with an alerts module to issue an alert to an external device. The difference frames and alerts may pass through a unidirectional “waterfall” link within the device, preventing access to the original video frames.

Abstract: A method and system for multi-spectral imagery acquisition and analysis, the method including capturing preliminary multi-spectral aerial images according to pre-defined survey parameters at a pre-selected resolution, automatically performing preliminary analysis on site or location in the field using large scale blob partitioning of the captured images in real or near real time, detecting irregularities within the pre-defined survey parameters and providing an output corresponding thereto, and determining, from the preliminary analysis output, whether to perform a second stage of image acquisition and analysis at a higher resolution than the pre-selected resolution.

Abstract: A lens compound for connecting to an interchangeable lens mount of a digital camera having a single image sensor, the lens compound including a body; a single mount connecting ring mounted on the body for connecting to the lens mount of the digital camera; at least two lenses of substantially identical focal length mounted in the body; and a different single or multi bandpass filter associated with each of the lenses, allowing the passage of at least one visible band and one non-visible band, selected from the group consisting of near infra-red bands and ultra violet bands of light, through the filters to the sensor; wherein the lenses are of substantially identical field of view and substantially identical image circle at a sensor plane of the image sensor.

Abstract: A method of editing a video container format file. The method comprises displaying media content hosted in a video container format file stored in a segment of a memory of a client terminal, receiving editing instructions indicative of changes to the media content, adding and/or activating video editing objects with the editing instructions to the video container format file while the video container format file remains stored in the segment, and decoding the video editing objects and the media content. The decoding is performed by editing the media content according to said editing instructions in the video editing objects.

Abstract: A method of generating a video container format file. The method comprises receiving a still image depicting a scene, receiving at least one object pertaining to the scene, encoding the still image as at least one video block of a video container format file, encoding the at least one object as data of the video container format file, and outputting the video container format file.

Abstract: A method for digital video image stabilization, the method including: estimating, from at least one portion of a frame, global frame displacement between an initial reference digital video frame and a current frame in a video sequence of frames; verifying, for the entire frame, the validity of the estimated frame displacement; and compensating for the estimated frame displacement by aligning at least one frame in the sequence with respect to the initial reference frame; wherein the step of aligning includes producing a corrected motion vector for the frame to be aligned and displacing the frame within the video frames sequence in accordance with the corrected motion vector.
