Atlanta tech firm Flock Safety secured a business license last month to install and maintain compact cameras across the state, after a years-long battle with state regulators. The cameras ...
In the visual effects industry, camera auto-calibration is often part of the "Match Moving" process where a synthetic camera trajectory and intrinsic projection model are solved to reproject synthetic content into video. Camera auto-calibration is a form of sensor ego-structure discovery; the subjective effects of the sensor are separated from ...
Current cameras feature abilities such as motion detection and two-way audio, allowing users to receive notifications of activity and speak and listen through the camera. Home surveillance cameras used for security purposes have become more accessible, but have sparked security concerns from consumers.
Modern digital television camera with a DIGI SUPER 86II xs lens from Canon. A professional video camera (often called a television camera even though its use has spread beyond television) is a high-end device for creating electronic moving images (as opposed to a movie camera, that earlier recorded the images on film).
Polishing is the process of creating a smooth and shiny surface by rubbing it or by applying a chemical treatment, leaving a clean surface with a significant specular ...
The development of the film required the photographer pull two tabs, the second tab which pulled the positive/negative "sandwich" from the camera, where it developed outside the camera. If the temperature was below 15 °C (60 °F), the positive/negative "sandwich" was placed between two aluminum plates and placed either in the user's pocket or ...
Electropolishing, also known as electrochemical polishing, anodic polishing, or electrolytic polishing (especially in the metallography field), is an electrochemical process that removes material from a metallic workpiece, reducing the surface roughness by levelling micro-peaks and valleys, improving the surface finish.
While used less extensively than traditional mechanical polishing, electropolishing is an alternative form of polishing that uses the principles of electrochemistry to remove microscopic layers of metal from a base surface. [3] This method of polishing can be fine-tuned to give a wide range of finishes, from matte to mirror-bright.
