Application of image technology

Optical Character Recognition

Optical Character Recognition (OCR) refers to the process of analyzing and recognizing the image files of text data to obtain the text and layout information. The processing process mainly includes five steps: input, pre-processing, mid-processing, post-processing, and output. The pre-processing includes: binarization, image noise reduction, skew correction; The mid-stage processing includes: layout analysis, character cutting, character recognition, layout restoration.

Remote sensing image

Remote sensing, unlike in situ observations, acquires information about an object or phenomenon without actual contact with the object. Remote sensing is used in many fields, including geography, land surveying, and most earth science disciplines (e.g., hydrology, ecology, meteorology, oceanography, glaciology, geology); It also has military, intelligence, commercial, economic, planning, and humanitarian applications.
