Class DefaultBlurEstimator

io.scanbot.sdk.process.DefaultBlurEstimator

All Implemented Interfaces:

BlurEstimator

public class DefaultBlurEstimator
implements BlurEstimator

Default implementation for interface BlurEstimator

Estimates blurriness of images.

The result is a 0..1 float, where 0 means a sharp image and 1 is most blurred one.

Method Detail

estimate

public float estimate(@NotNull
                      kotlin.Array[] nv21,
                      int width,
                      int height,
                      int orientation)

Run blur estimation on given nv21 image.

Returns:

sharpness of image: 0 is sharp, 1 is blurred.

estimateInBGR

public float estimateInBGR(@NotNull
                           kotlin.Array[] bgr,
                           int width,
                           int height,
                           int orientation)

Run blur estimation on given byte-array-encoded image.

Returns:

sharpness of image: 0 is sharp, 1 is blurred.

estimateInJPEG

public float estimateInJPEG(@NotNull
                            kotlin.Array[] jpeg,
                            int width,
                            int height,
                            int orientation)

Run blur estimation on given jpeg-encoded byte array image.

Returns:

sharpness of image: 0 is sharp, 1 is blurred.

estimateInBitmap

public float estimateInBitmap(@NotNull
                              android.graphics.Bitmap bitmap,
                              int orientation)

Run blur estimation on given Bitmap image.

Returns:

sharpness of image: 0 is sharp, 1 is blurred.
