Abstract
Image classification techniques are described for adjustment of an image. In one or more implementations, an image is classified by one or more computing device based on suitability of the image for adjustment to correct perspective distortion of the image. Responsive to a classification of the image as not suitable for the adjustment, suitability of the image is detected for processing by a different image adjustment technique by the one or more computing devices.
Claims20
A method implemented by one or more computing devices, the method comprising:
- classifying an image based on suitability of the image for adjustment by an image adjustment technique to correct perspective distortion of the image;
- and
- responsive to the classifying of the image as not suitable for the adjustment, detecting suitability of the image for processing by a different image adjustment technique.
One or more computer-readable storage media comprising instructions stored thereon that, responsive to execution by a computing device, causes the computing device to perform operations comprising:
- classifying an image based on suitability of the image for upright adjustment, the classifying comprising:
- analyzing edge pixels and line pixels in the image;
- analyzing line pixels and vanishing line pixels in the image;
- or
- analyzing vertical and horizontal vanishing lines in the image;
- and
- responsive to the classifying of the image as suitable for upright adjustment, performing one or more upright adjustment operations on the image that correct perspective distortion of the image.
A system comprising:
- at least one module implemented at least partially in hardware, the at least one module configured to classify an image based on suitability of the image for upright adjustment;
- and
- one or more modules implemented at least partially in hardware, the one or more modules configured to perform one or more upright adjustment operations on the image that correct perspective distortion of the image responsive to the classification of the image as suitable for upright adjustment.
