A method of price text detection by an imaging controller comprises obtaining, by the imaging controller, an image of a shelf supporting labels bearing price text, generating, by the imaging controller, a plurality of text regions containing candidate text elements from the image, assigning, by the imaging controller, a classification to each of the text regions, selected from a price text classification and a non-price text classification. The imaging controller, within each of a subset of the text regions having the price text classification: detects a price text sub-region and generates a price text string by applying character recognition to the price text sub-region. The method further includes presenting, by the imaging controller, the locations of the subset of text regions, in association with the corresponding price text strings.

A method of character recognition is implemented by an electronic device to recognize, in an image representing an object comprising at least one raised character, called a basic image, at least one raised character of the basic image. The method includes: a phase of processing at least one image, the phase including at least one implementation of a Phong reflection module and delivering at least one identification image; and a phase of identifying characters as a function of the basic image and the at least one identification image.

The invention discloses a powder leakage monitoring device and a powder leakage monitoring method. The powder leakage monitoring device comprises light field camera, 3D PTZ (3-Dimensional Pan/Tilt/Zoom) and computer. Wherein, the light field camera records original light field images of monitored area; the 3D PTZ under the light field camera adjusts the shooting angle of the light field camera when it rotates according to the set direction; and the computer respectively connects to the light field camera and the 3D PTZ, which generates refocused images corresponding to the original light field images, and determines the spatial coordinates of the powder leakage point and the hazard range of the powder leakage in the monitored area according to the refocused images and the shooting angle. Therefore, the range and accuracy of powder leakage monitoring are both increased by using this invention.

To carry out trading card assessment swiftly and with high accuracy. A program causing a computer to execute: a step of accepting input of a card type of a target trading card; a step of extracting a feature image including a specific design pattern from a card image obtained by optically reading a target trading card and determining the series to which the target trading card belongs based on the extracted feature image; a step of determining the content of the target trading card by extracting a feature amount from the card image of the target trading card and collating the extracted feature amount with a feature database; and a step of displaying on a display device the content of the target trading card.

Presented herein are systems and methods for the employment of machine learning models for image processing. A mobile application for client-side image processing and validation, which interacts with and leverages native image processing software of the client device, where the image processing software and the mobile application include any number of machine-learning models for identifying a document and attributes of the document for recognition and validation. This mobile application uses the image processing software from a client operating system to control the camera. The image processing software generates various types of information about a video frame and the document, and the mobile application invokes APIs or software libraries of the image processing software to access the information and validate the frame and document.
