Abstract
An edge device can include a processing device, an image sensor, and a memory having instructions that are executable by the processing device for causing the processing device to perform operations. The processing device can receive, from the image sensor, an image of an environment. The processing device can determine a visibility measure corresponding to the environment by determining a dark channel of the image, determining, based on the dark channel of the image, a transmission map of the image, and determining, based on the transmission map, a visual contrast of the image. The processing device can generate information corresponding to the visibility measure.
Claims13
An edge device comprising:
- a processing device;
- an image sensor;
- and
- a memory having instructions that are executable by the processing device for causing the processing device to:
- receive, from the image sensor, an image of an environment;
- determine a visibility measure corresponding to the environment by:
- determining a dark channel of the image;
- determining, based on the dark channel of the image, a transmission map of the image;
- and
- determining, based on the transmission map, a visual contrast of the image;
- and
- generate information corresponding to the visibility measure.
A non-transitory computer-readable medium comprising instructions that are executable by a processing device for causing the processing device to:
- receive, from an image sensor, an image of an environment;
- determine a visibility measure corresponding to the environment by:
- determining a dark channel of the image;
- determining, based on the dark channel of the image, a transmission map of the image;
- and
- determining, based on the transmission map, a visual contrast of the image;
- and
- generate information corresponding to the visibility measure.
