Image Decode Implementation with CV2 and nvjpeg
author: junjie.jiang
Description
An image decode operator implementation with OpenCV and nvjpeg. In CPU env, use OpenCV, in GPU env, use nvjpeg to decode jpeg files.
Code Example
Load a image from path './src_dog.jpg'.
Write the pipeline in simplified style:
from towhee.dc2 import pipe, ops, DataCollection
p = (
pipe.input('url')
.map('url', 'image', ops.image_decode.nvjpeg())
.output('image')
)
DataCollection(p('./src_dog.jpg')).show()
Factory Constructor
Create the operator via the following factory method:
ops.image_decode.nvjpeg()
Interface
An image decode operator takes an image path as input. It decodes the image back to ndarray.
Parameters:
img: str
Local file path or http url.
Returns: towhee.types.Image (a sub-class of numpy.ndarray)
The decoded image data as numpy.ndarray.
