Acquired Portfolios

This lot is generally related to three-dimensional (3D) imaging using a mobile device. Techniques are disclosed to capture 3D images through a mobile phone to detect structural defects and analyze goods without physical presence, such as body scanning, garment fitting, medical imaging, etc. Disclosed is a technique for a 3D-imaging system consisting of a light source, and a modulator connected with the light source to modulate output of the light source with a frequency sweep signal. Also disclosed is an optical circuitry connected to the light source and a light sensor circuitry for sensing optical output of the optical circuitry. The optical circuitry converts the optical output into multiple electrical signals. Further disclosed is a signal processing circuit connected with the light sensor circuitry for extracting 3D information of the object from the electrical signals. Few techniques disclose a mobile phone for conveniently capturing high resolution 3D images that contain the depth information. The technology may be implemented in 3D imaging, fingerprint sensors, mobile phones, iPads, digital cameras, etc.

This lot is generally related to image processing. Disclosed is a device for real time motion detection in an image by using a sub-sampling module to sub-sample current and previous images, perform census transform on each sub-sample to obtain a census vector, calculate and compare correlation values between the current image and the previous images based on the census vector and detect a region having the highest correlation to detect motion information. The technology may be implemented in robot vision, intelligent cameras, or industrial fields.

These patents are generally related to imaging systems. First set of patents disclose techniques to provide human behaviour recognition systems by studying human body gestures. Second set of patents disclose techniques to provide human gesture recognition systems to control self-service machines. Third set of patents disclose techniques to provide real-time computer vision systems to track moving objects in a scene where the systems use novel algorithms to locate the objects without using any search procedures.
