A printing system includes a product inspection unit configured to perform product inspection on a print product based on a scanned image generated by reading the print product with an image printed thereon and correct answer images stored in advance, a post-processing unit configured to perform post-processing on the print product, and a control unit configured to, upon occurrence of a jam in the print product, control the printing unit to perform reprinting, wherein, upon occurrence of a jam while the post-processing is performed, the product inspection unit is notified of identification information regarding the print product on which printing is started by the reprinting, and wherein, based on the identification information, the product inspection unit references any of the correct answer images corresponding to a scanned image generated by the reprinting and performs the product inspection on the print product.

According to aspects of the present disclosure, when a print instruction is input from an editing application to a general-use printing program, and image data included in the print instruction contains barcode information indicating a barcode, a support program corresponding to a printer generates substitute image. The substitute image is generated by the general-use printing program and substitutes for an image of the barcode.

Disclosed is an anti-counterfeiting and encryption method based on a local random image transformation technique, which belongs to the technical field of anti-counterfeiting and encryption. In the present disclosure, local replacement is performed on random images (that is, the arrangement structure of pixels in a space is changed or pixel values are changed), and then, two random images are used to store corresponding information; and “locally scrambled” portions of the images contain a part of key information. However, since the images are still random, there is still no explicit information display in the images; and even if the information is intercepted during a transfer process, the content of the information cannot be known without the original first random scatter plot, and the existing information also cannot be tampered with. In the present disclosure, a user does not need to memorize any password.

A method includes obtaining multiple video frames. The method also includes determining whether a bi-directional optical flow between the multiple video frames satisfies an image quality criterion for bi-directional consistency. The method further includes identifying a non-linear curve based on pixel coordinate values from at least two of the video frames. The at least two video frames include first and second video frames. The method also includes generating interpolated video frames between the first and second video frames by applying non-linear interpolation based on the non-linear curve. In addition, the method includes outputting the interpolated video frames for presentation.

An apparatus includes at least one processing device configured to obtain input frames from a video. The at least one processing device is also configured to generate a forward flow from a first input frame to a second input frame and a backward flow from the second input frame to the first input frame. The at least one processing device is further configured to generate an occlusion map at an interpolated frame coordinate using the forward flow and the backward flow. The at least one processing device is also configured to generate a consistency map at the interpolated frame coordinate using the forward flow and the backward flow. In addition, the at least one processing device is configured to perform blending using the occlusion map and the consistency map to generate an interpolated frame at the interpolated frame coordinate.

Sparse signal modulation schemes encode a data channel on a substrate in a manner that is robust, flexible to achieve perceptual quality constraints, and provides improved data capacity. The substrate is printed by any of a variety of means to apply the image, with sparse signal, to an object. After image capture of the object, a decoder processes the captured image to detect and extract data modulated into the sparse signal. The sparse signal may incorporate implicit or explicit synchronization components, which are either formed from the data signal or are complementary to it.

An image processing apparatus including: a pattern detecting section which detects a specific pattern in an image; an image holding section which holds the image; an image conversion section which converts a pattern in the image into a pattern different from the specific pattern; and an output switching section which outputs an image having the pattern converted by the image conversion section for a region where the specific pattern is detected by the pattern detecting section, and outputs the image held by the image holding section for a region where the specific pattern is not detected.

A computer-implemented method, system and computer program is disclosed. The method may comprise providing an image comprising a plurality of pixels, identifying at least one portion of the image to be obfuscated, modifying pixels of the at least one image portion using a key for producing an updated image in which the at least one image portion is obfuscated, providing the key, or a link to the key, in an access profile for the identified at least one image portion and allocating permissions to one or more users for enabling them to view the at least one image portion, by use of the key, when viewing the updated image.
