tools for image conversion

vision_stuff

Tools for image conversion, which seems to be useful, at least for me.

Info

Collection of functions for convertion images with python opencv. For now one useful function is shrink_image and its derivative shrink_and_store_images_dir. It let us to shrink image(s), to specified size. Useful, when we have a couple of different shape images and want all of them to be e.g. 640x640.

Install

.. code-block:: python

pip install vision_stuff

Usage from python

.. code-block:: python

from vision_stuff import shrink_image

# example
img = cv2.imread('image_to_be_shrinked.png', 1)
out = shrink_image(img, 400, 400)
cv2.imwrite('out.png', out)

.. code-block:: python

from vision_stuff import shrink_and_store_images_dir

directory = 'different_shape_images'
shrink_and_store_images_dir(directory, width=640, height=640, resize=True)
# it convert images and store them into new directory named (directory + "_converted")
