Class NoUpScalingDewarpPolicy

  • public final class NoUpScalingDewarpPolicy
    extends DewarpPolicy
    No upscaling dewarp policy. Dewarp height will be calculated in a way that no part of image will be up-scaled. However, if dewarp height calculated in this way is larger than value defined by maxAllowedDewarpHeight, then maxAllowedDewarpHeight will be used for dewarp height, effectively scaling down the image. This policy is usually best for processor groups that use DEEP OCR, hologram detection or NN-based classification.
