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 the 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.
