An image analysis method is applied to estimating a mounting position of a camera and includes utilizing the camera to capture an image toward a target region. The image includes at least one object of interest. The object of interest has a pixel height in the image. The image analysis method further includes obtaining an inclining angle and a rolling angle of the camera relative to the target region, calculating a mounting height of the camera relative to the target region according to an input height and the pixel height of the object of interest, an image capturing parameter of the camera, the inclining angle and the rolling angle, and performing video content analysis on the image according to the image capturing parameter, the inclining angle, the rolling angle and the mounting height of the camera.

Integrated but detachable mini-camera for a mobile device. The mobile device comprises a main body and a detachable mini-camera configured to attach to and detach from a socket in the main body. The detachable mini-camera may comprise at least one camera and a rechargeable battery configured to, while the detached mini-camera is attached to the main body, charge from a battery in the main body via the socket. While the detachable mini-camera is detached from the main body, a wireless transceiver in the detachable mini-camera wirelessly communicates with a wireless transceiver in the main body, and a mobile application, executed by a processor in the main body, controls the detachable mini-camera and receives image data from the detachable mini-camera via the wireless communication.

A multifocal test system is described herein. The system includes a plurality of displays located at different focal distances. Each display includes a plurality of pixels with pixel intensity values. The system includes an eye tracking system that determines eye tracking information about a position of an eye relative to the displays. A controller is configured to determine pixel intensity values based on decomposition of a scene across the plurality of displays, and the position of the eye.

Based on viewing tracking data, a viewer's view direction to a three-dimensional (3D) scene depicted by a first video image is determined. The first video image has been streamed in a video stream to the streaming client device before the first time point and rendered with the streaming client device to the viewer at the first time point. Based on the viewer's view direction, a target view portion is identified in a second video image to be streamed in the video stream to the streaming client device to be rendered at a second time point subsequent to the first time point. The target view portion is encoded into the video stream with a higher target spatiotemporal resolution than that used to encode remaining non-target view portions in the second video image.

Systems, apparatuses, and methods are described which provide a camera mount system. A camera mount is in communication with a positioning device. The positioning device has a compass, gyroscope, and emits an infrared light beam. The camera mount has a sensor that receives reflected and/or scattered infrared light from a moving target. The camera mount changes its orientation based on information from its sensor, and gyroscope and compass information from the positioning device.

The technology disclosed relates to relates to providing command input to a machine under control. It further relates to gesturally interacting with the machine. The technology disclosed also relates to providing monitoring information about a process under control. The technology disclosed further relates to providing biometric information about an individual. The technology disclosed yet further relates to providing abstract features information (pose, grab strength, pinch strength, confidence, and so forth) about an individual.

A method for identifying an inventory item is provided. The method includes using first one or more sensors to produce first one or more outputs indicative of an inventory item, using second one or more sensors to produce second one or more outputs indicative of the inventory item, generating, based on the first one or more outputs and independent of the second one or more outputs, a first confidence level of the inventory item being a first inventory item, generating, based on the second one or more outputs and independent of the first one or more outputs, a second confidence level of the inventory item being a second inventory item, and identifying, based on the first confidence level and the second confidence level, the inventory item as one of the first inventory item or the second inventory item.
