Abstract
A processor-implemented method of generating feature data includes: receiving an input image; generating, based on a pixel value of the input image, at least one low-bit image having a number of bits per pixel lower than a number of bits per pixel of the input image; and generating, using at least one neural network, feature data corresponding to the input image from the at least one low-bit image.
Claims20
A processor-implemented method of generating feature data, the method comprising:
- receiving an input image;
- generating N binary images from the input image, wherein N is the number of bits per pixel of the input image, wherein N is an integer equal to or greater than 2;
- and
- generating, using at least one neural network, feature data corresponding to the input image from the N binary images.
A processor-implemented method of generating feature data, the method comprising:
- receiving a feature map of an input image including pixels having a plurality of bit value levels;
- generating, for each of the bit value levels, a binary feature map including binary pixel values corresponding to pixels of the feature map that include a bit of the bit value level;
- and
- generating, using a neural network, feature data corresponding to the input image based on the generated binary feature maps.
An apparatus for generating feature data, the apparatus comprising:
- one or more processors configured to:
- receive an input image;
- generate N binary images from the input image, wherein N is the number of bits per pixel of the input image, wherein N is an integer equal to or greater than 2;
- and
- generate, using at least one neural network, feature data corresponding to the input image from the N binary images.
