Field Detail

ORIGINAL

public static final ImageType ORIGINAL

This is the original image that arrived from camera. If scanning region is set, you should also check getRoi method of the Image object because usually original images are in YUV_NV21 format.

SUCCESSFUL_SCAN

public static final ImageType SUCCESSFUL_SCAN

This is the original image that arrived from camera that was used to recognize item. If scanning region is set, you should also check getRoi method of the Image object because usually original images are in YUV_NV21 format.

DEWARPED

public static final ImageType DEWARPED

This is the dewarped image that is obtained after performing perspective correction of the detected item. This image is usually in format BGRA_888, but might also be in ALPHA_8. This image is not always available - this depends on enabled recognizers and their settings.

DEBUG_DETECTION

public static final ImageType DEBUG_DETECTION

This is the image that was used as scratch surface to display document detection process (if any). It is generally used for debugging detection process.

DEBUG_OCR_INPUT

public static final ImageType DEBUG_OCR_INPUT

This is grayscale image preprocessed with OCR engine. This is the image that will be used for segmentation and classification of characters. It is generally used for debugging OCR process.

DEBUG_DEWARPED

public static final ImageType DEBUG_DEWARPED

This is the dewarped image that is obtained after performing perspecitve correction of each element that needs to be scanned. This image is usually in format ALPHA_8, but sometimes can also be in BGRA_8888.

DEBUG_MARKED_DEWARPED

public static final ImageType DEBUG_MARKED_DEWARPED

This is same as DEBUG_DEWARPED, except it also contains visualisation of OCR result layered onto image. This image is always in BGRA_8888 format.
