Simple Installation for JavaScript
Image Recognition with JavaScript
The widespread adoption of OCR applications is usually stopped by the fact that scanners are not commonplace for most users. Our OCR library has powerful built-in image pre-processing filters that can handle dark, rotated, skewed, and noisy images. In combination with support for all image formats, it allows for reliable recognition of even smartphone photos. Most of the pre-processing and image correction is done automatically, so you will only have to intervene in difficult cases.
Apply automatic image corrections - JavaScript
// Load 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;
// Automatically adjust contrast and remove noise
var settings = Module.WasmAsposeOCRRecognitionSettings();
settings.detect_areas_mode = Module.DetectAreasMode.PHOTO;
settings.auto_contrast = true;
settings.auto_denoising = true;
// Extract text from photo:
var inputs = new Module.WasmAsposeOCRInputs();
inputs.push_back(input);
var result = Module.AsposeOCRRecognize(inputs, settings);
// Output recognition results
var result_str = Module.AsposeOCRSerializeResult(result, Module.ExportFormat.text);
console.log(result_str);
Universal image to text Converter for JavaScript
While many businesses, organizations and individuals have been actively working on reducing their reliance on paper documents, this is still the most widespread format for storage and sharing. Scanned documents backed by physical archives are sufficient for regulatory compliance, legal purposes, long-term backup and redundancy. However, business cases frequently arise for creating new content based on existing scanned content or portions of existing documents. Aspose.OCR for JavaScript via С++ makes it easy to convert a scanned page into a searchable and editable text. Content is recognized with high accuracy and speed, saving you the time and effort of manual typing and ensuring there are no human errors, especially when working with large volumes of information.
Convert image to document - JavaScript
// Load a scanned page 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 content structure
var settings = Module.WasmAsposeOCRRecognitionSettings();
settings.detect_areas_mode = Module.DetectAreasMode.DOCUMENT;
settings.upscale_small_font = true;
// Extract text from a page
var inputs = new Module.WasmAsposeOCRInputs();
inputs.push_back(input);
var result = Module.AsposeOCRRecognize(inputs, settings);
var editableText = Module.AsposeOCRSerializeResult(result, Module.ExportFormat.text);
Extracting numeric data from tables
When managing large printed tables containing numerical data, such as raw data of field sociological surveys or inventory lists, manual extraction becomes a sluggish, impractical process highly susceptible to human errors. OCR helps to automate and standardize the extraction of information, ensuring consistent and reliable results. Aspose.OCR for JavaScript via С++ fully automates conversion of scanned or photographed tabular data into machine-readable content. Extracted data can be easily integrated into databases and analyzed, contributing to more informed decision-making.
Table image to text - JavaScript
// 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);
