SDK installation

Note: In SDK 4.x and above document auto-scanning and facial recognition are powered by WASM technology. The WASM module is available in three variants to accommodate different levels of browser capabilities:

• uqudoScanModuleBasic: Supports all the basic features

• uqudoScanModuleAdvanced: Includes SIMD support

• uqudoScanModuleAdvancedWithThreads: Incorporates both SIMD and threading support

To support and load fastest option, uqudoScanModuleAdvancedWithThreads, the web server hosting the page with the web SDK must include the following HTTP response headers:

• Cross-Origin-Embedder-Policy = "require-corp"

• Cross-Origin-Opener-Policy = "same-origin"

Please refer to https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Cross-Origin-Embedder-Policy and https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Cross-Origin-Opener-Policy to understand the implications of enabling these headers.
