Provided is an information processing apparatus including: a marking extraction circuit that extracts, from a script image including a plurality of markings respectively superimposed on a plurality of character strings, the plurality of markings; a same-character-string identification circuit that identifies the same character string out of the plurality of character strings on which the markings are respectively superimposed; and a symbol determination circuit that allocates the same symbol to the same character string and allocates different symbols to different character strings.

A system for determining compression rates for images, the system comprising a processing resource configured to: obtain a given image at least partially comprising a given text; compress the given image at a given compression ratio, giving rise to a compressed image; perform Optical Character Recognition (OCR) on the compressed image, giving rise to OCR text; compare the OCR text to the given text, giving rise to comparison results; upon the comparison results meeting a rule, increase the given compression rate; and upon the compression results not meeting a rule, return to a previous compression rate, if any.

An image forming apparatus includes a communication interface, an encoder, and a processor. The communication interface communicates with a cloud server that executes decoding by any of a plurality of decoding methods corresponding to a plurality of autoencoder models. The encoder performs encoding by any of a plurality of encoding methods corresponding to the plurality of autoencoder models. The processor specifies an encoding method to the encoder to encode image data into intermediate layer data that is configured to be decoded by the cloud server and transmits the intermediate layer data and model information indicating the specified encoding method used for the encoding to the cloud server through the communication interface.

An image compression method includes: starting a social media application to enter an interface for inputting a to-be-posted content; when an operation for adding an image is detected, displaying a first image in the interface; and when an operation for posting the first image is detected, in response to the operation, performing differential compression on the first image to obtain a second image, and sending the second image to a server corresponding to the social application. The method enables an electronic device to perform differential compression on the image and post the compressed image on a social media platform.
