DLImageResize Documentation

Current Version: DLImageResize v1.0

DLImageResizeDOCLIB is a DOCLIB add-on module that computes a rescaled representation of an input DLImage and returns its resized grayscale version using the Lanczos filter. The algorithm works best for native grayscale images as it makes use of grayscale information.

Input binary and color images are also supported by DLImageResizeDOCLIB. However, they are converted to grayscale images first before processing. The rescaling algorithm preserves fine details of the input document image, especially on edges and contours.



DLImageResize Library is an add-on module of DOCLIB. DOCLIB is being developed under contract by a collaboration between:

The Laboratory for Language and Media Processing
Unviersity of Maryland, College Park
and
