About This Product

This is a dedicated image preprocessing module included with our decoding library products. To accurately decode various codes, it is necessary to capture clear images, but preprocessing to create the optimal image is also important. In addition to inversion processing such as binarization, which converts the image into two colors of white and black, image pre-image processing such as emphasizing feature points (expansion/contraction, etc.), blurring to reduce noise components, and correcting distortion. Processing is key. This makes it possible to implement the optimal preprocessing (image processing) functions required for reading.

■Features

・Pre-processing function for 8-bit monochrome images available ・Written in ANSI-C, OS/platform independent design ・Comes with a Windows simulator that is convenient for adjustments

■Function list

・Binarization using threshold (black and white) ・Upside down ・Left and right reversal ・Black and white inversion ・Linear interpolation expansion ・Blur 1 (box) ・Blur 2 (out of focus) ・Contour enhancement (unsharp mask) ・Distortion correction ・Dark area expansion (light area contraction) ・Bright area expansion (dark area contraction) ・Brightness smoothing 1 (gamma correction) ・Brightness smoothing 2 (morphological conversion) ・Subtraction
