Image Decode Implementation with CV2

author: Kaiyuan Hu, Rentong Guo

Desription

An image decode operator implementation with OpenCV.

import towhee import ops

img_decode = ops.image_decode.cv2()
img = img_decode('./dog.jpg')

Factory method

Create the operator via the following factory method

ops.image_decode.cv2()

Interface

An image decode operator takes an image path as input. It decodes the image back to ndarray.

Parameters:

​ img: str

​ Image file path.

Returns: numpy.ndarray

​ The decoded image data.

Code Example

Load a image from path './dog.jpg'.

Write the pipeline in simplified style:

import towhee.DataCollection as dc

dc.glob(./dog.jpg)
  .image_decode.cv2()
  .show()

Write a same pipeline with explicit inputs/outputs name specifications:

import towhee.DataCollection as dc

dc.glob['path'](./dog.jpg)
  .image_decode.cv2['path', 'img']()
  .select('img')
  .show()
