Image to Text Recognition with Node.js
Node.js OCR allows to transform table images into editable text, streamlining data extraction. Ideal for various business cases, our powerful OCR solution enhances data accessibility, improving productivity in applications.
Setup Table image to text conversion - Node.js
// Load a scan or photo from user input
const fileData = new Uint8Array(e.target.result);
let filename = file.name;
let stream = Module.FS.open(filename, "w+");
Module.FS.write(stream, fileData, 0, fileData.length, 0);
Module.FS.close(stream);
var input = Module.WasmAsposeOCRInput();
input.url = filename;
// Analyze tabular structures
var settings = Module.WasmAsposeOCRRecognitionSettings();
settings.detect_areas_mode = Module.DetectAreasMode.TABLE;
// Limit the subset of characters to improve recognition accuracy and increase performance
settings.alphabet = "1234567890.,;";
// Extract text from a table
var inputs = new Module.WasmAsposeOCRInputs();
inputs.push_back(input);
var result = Module.AsposeOCRRecognize(inputs, settings);
var editableText = Module.AsposeOCRSerializeResult(result, Module.ExportFormat.text);
