EnumGrayscaleEnhancementMode

EnumGrayscaleEnhancementMode is an enumeration that determines which grayscale enhancement modes the library will apply before the detection process to improve the read rate of the barcodes in a given image or frame.

Member Description
GEM_SKIP Disables any grayscale image preprocessing. Selecting this mode skips the preprocessing step, passing the image through to subsequent operations without modification.
GEM_AUTO Automatic selection of grayscale enhancement mode which is currently not supported. Future implementations may automatically choose the most suitable enhancement based on image analysis.
GEM_GENERAL Uses the original, unprocessed image for subsequent operations. This mode is selected when no specific grayscale enhancement is required, maintaining the image in its natural state.
GEM_GRAY_EQUALIZE Applies a grayscale equalization algorithm to the image, enhancing contrast and detail in gray level. Suitable for images with poor contrast.
GEM_GRAY_SMOOTH Implements a grayscale smoothing algorithm to reduce noise and smooth the image. This can be beneficial for images with high levels of grain or noise.
GEM_SHARPEN_SMOOTH Enhances the image by applying both sharpening and smoothing algorithms. This mode aims to increase clarity and detail while reducing noise, offering a balanced approach to image preprocessing.
