The present disclosure discloses a picture recognition method performed by a computing device. The method includes: obtaining a recognized current string and a hash value of the current string during text recognition for an acquired image through an optical character recognition model, and storing the current string and the hash value of the current string into a first preset tree structure and a second preset tree structure; predicting a new probability value of the current string at a next moment, to obtain an extended string set; obtaining N strings with the highest probability value according to the hash value stored in the second preset tree structure and retaining the N strings; and using the N strings as the current strings, repeating the foregoing steps until recognition of all acquired images is completed, and obtaining a string with the highest probability value as a final recognition result.

Various embodiments provide processes for identification of embedded unauthorized data within document data. Such processes may include evaluating document data properties for indications of closing headers, comparing document data sizes against reference sizes, and comparing document data sizes against other document data sizes. Certain embodiments evaluating image data may evaluate image properties, such as histograms or gradient images, to determine random or otherwise unauthorized data. Upon detection of unauthorized data, the document data may be flagged for later processing, such as removal from a storage server.

A non-Lambertian surface inspection system for line scan is proposed. Such a system includes: a surface inspection part including a frame provided with a curved mounting hole formed on at least one of one surface and the other surface thereof and a photographing hole formed at an upper end thereof, and a plurality of first and second illumination modules installed in the mounting hole and output light in oblique lines toward an inspection object placed on a bottom surface thereof; a camera positioned above the photographing hole to photograph the inspection object positioned on the bottom surface through the photographing hole and receive an entire reception image including first and second illumination images; and a controller to control operation of the camera, selectively operate the first illumination module and the second illumination module, and extract the first illumination image and the second illumination image.

A system for regulating fluid flow having a processor configured to reduce image noise is provided. The system includes an image sensor to capture an image of the drip chamber. The processor captures the image of the drip chamber using the image sensor, performs an edge detection on the image to generate a first processed image, and performs a Boolean-operation on a pixel on a first side of an axis of the first processed image with a corresponding pixel on a second side of the axis of the first processed image to generate a second processed image.

An apparatus, system and method for regulating fluid flow are disclosed. The apparatus includes a flow rate sensor and a valve. The flow rate sensor uses images to estimate flow through a drip chamber and then controls the valve based on the estimated flow rate. The valve comprises a rigid housing disposed around the tube in which fluid flow is being controlled. Increasing the pressure in the housing controls the size of the lumen within the tube by deforming the tube, therefore controlling flow through the tube.
