How do I read a file in MATLAB?

Use fopen to open the file, specify the character encoding, and obtain the fileID value. When you finish reading, close the file by calling fclose(fileID) . A = fscanf( fileID , formatSpec , sizeA ) reads file data into an array, A , with dimensions, sizeA , and positions the file pointer after the last value read.

Which algorithm is used to detect text in images?

Optical Character Recognition (OCR)
Optical Character Recognition (OCR) is used to analyze text in images. The proposed algorithm deals with taking scanned copy of a document as an input and extract texts from the image into a text format using Otsu’s algorithm for segmentation and Hough transform method for skew detection.

    Image to read, specified as an integer scalar or, for GIF files, a vector of integers. For example, if idx is 3, then imread returns the third image in the file. For a GIF file, if idx is 1:5, then imread returns only the first five frames. The idx argument is supported only for multi-image GIF, CUR, ICO, and HDF4 files.. When reading multiple frames from the same GIF file, specify idx as a
