Caer - Modern Computer Vision on the Fly

Caer is a lightweight, high-performance Vision library for high-performance AI research. We wrote this framework to simplify your approach towards Computer Vision by abstracting away unnecessary boilerplate code giving you the flexibility to quickly prototype deep learning models and research ideas. The end result is a library quite different in its design, that’s easy to understand, plays well with others, and is a lot of fun to use.

Our elegant, type-checked API and design philosophy makes Caer ideal for students, researchers, hobbyists and even experts in the fields of Deep Learning and Computer Vision.

Overview

Caer is a Python library that consists of the following components:

Component Description
caer A lightweight GPU-accelerated Computer Vision library for high-performance AI research
caer.color Colorspace operations
caer.data Standard high-quality test images and example data
caer.path OS-specific path manipulations
caer.preprocessing Image preprocessing utilities.
caer.transforms Powerful image transformations and augmentations
caer.video Video processing utilities

Usually, Caer is used either as:

  • a replacement for OpenCV to use the power of GPUs.
  • a Computer Vision research platform that provides maximum flexibility and speed.

Installation

See the Caer Installation guide for detailed installation instructions (including building from source).

Currently, caer supports releases of Python 3.6 onwards; Python 2 is not supported (nor recommended). To install the current release:

$ pip install --upgrade caer

Getting Started

Minimal Example

import caer

# Load a standard 640x427 test image that ships out-of-the-box with caer
sunrise = caer.data.sunrise(rgb=True)

# Resize the image to 400x400 while MAINTAINING aspect ratio
resized = caer.resize(sunrise, target_size=(400,400), preserve_aspect_ratio=True)

caer.resize()

For more examples, see the Caer demos or Read the documentation
