There is disclosed herein methods for measuring reproducing capability of image recording and reproducing devices. The method includes generating an image of a test panel, wherein the image was captured by a test device (e.g., capturing the test image with the test device and uploading the same to a computer processing device; or electronically receiving the test image at a processing device). The image comprises a digital image including therein the test panel. The image is compared to a reference image of a reference panel.

Disclosed are an abnormality detection method, a network video recorder (NVR) and a video server. The method includes: an NVR receiving first keep-alive information from a front-end apparatus, the first keep-alive information carries first verification information, and the first verification information is generated according to a process run by the front-end apparatus while sending the first keep-alive information; the NVR carrying the first verification information in second keep-alive information, and sending the same to the video server; the video server determining, according to the first verification information and second verification information of the front-end apparatus, whether an abnormality has occurred in the front-end apparatus, the second verification information is generated according to a process run by the front-end apparatus in a normal operation status.

The present invention provides a system for accurate three-dimensional (3D) capture of apparel by 3D scanning and stereo photogrammetry. One or more flexible deflated bladders are inserted into an apparel and inflated by a filling media source. The bladder is inflated to measure at least one of size of the apparel, tensile strength of the fabric of the apparel, or cross section perimeter of the apparel. A rotating structure is anchored onto the stable structure to uniformly rotate all the fixed points of the apparel. One or more 3D scanners are configured to scan the inflated apparel on the stable structure and export the scanned data to one or more software applications. The processor retrieves the 3D scanned dimensional data from a searchable database and compares the given apparel's dimensions with one or more apparels' dimensions in the database to provide the customer with size recommendation via a display.

Methods and systems for detecting and monitoring memory card performance characteristics. A method for detecting memory card performance characteristics includes obtaining at least one memory card performance characteristic from a memory card when the memory card is inserted in an image capture device, determining whether the at least one memory card performance characteristic meets a defined image capture device requirement, and providing an alert when the at least one memory card performance characteristic fails to match the defined image capture device requirement.
