Computer vision has gained tremendous traction thanks to state-of-the-art tools and technologies that seem to be released every day. This technology is being applied in various fields, including autonomous vehicles, robotics, and medical image analysis. 

Computer vision is a scientific field that involves using technology to understand images and videos. The goal is to automate vision tasks that would otherwise be done by human beings. Some of the common tasks that are being automated include:

  • Image classification: this involves classifying the contents of an image 
  • Object detection: that involves identifying objects in images and drawing bounding boxes around them 
  • Semantic segmentation: that entails identifying the class of every pixel in an image and drawing a mask around each object
  • Human Pose estimation: that identifies the pose of a person in an image of a video 

Just to mention a few. 

Automation of these tasks has been enabled by the latest advances in deep learning and machine learning. Particularly, convolutional neural networks have played a big role in furthering computer vision. These networks are able to detect and extract important features in an image. These features are then used to identify objects and classify images. 

In this article, we are going to take a look at some of the top tools and technologies that have enabled these computer vision applications. 

Frameworks and libraries

There are numerous computer vision frameworks and libraries. These tools do different things in the computer vision realm. Each has its advantages and disadvantages. Let’s take a look! is a platform that can be used for logging and managing computer vision model metadata. You can use it to log:

The library also provides interfaces for CUDA and OpenCL. OpenCV can also be used in C++, Java, MATLAB, and Python. Some of the tasks that can be accomplished using OpenCV include: 

  • Classifying human actions in videos
  • Object identification 
  • Tracking moving objects 
  • Counting people 
  • Detecting and recognizing faces 

OpenCV can also be used for processing images for computer vision. Some of the supported tasks include: 

  • Changing the color spaces
  • Smoothing images 
  • Blending images using image pyramids 
  • Image segmentation using the watershed algorithm 

For instance, here is how you can perform a Fourier Transformation on an image.

import numpy as np
import cv2 as cv
from matplotlib import pyplot as plt
img = cv.imread('f.jpg',0)
dft = cv.dft(np.float32(img),flags = cv.DFT_COMPLEX_OUTPUT)
dft_shift = np.fft.fftshift(dft)
magnitude_spectrum = 20*np.log(cv.magnitude(dft_shift[:,:,0],dft_shift[:,:,1]))
plt.subplot(121),plt.imshow(img, cmap = 'gray')
plt.title('Input Image'), plt.xticks([]), plt.yticks([])
plt.subplot(122),plt.imshow(magnitude_spectrum, cmap = 'gray')
plt.title('Magnitude Spectrum'), plt.xticks([]), plt.yticks([])

TensorFlow is an open-source deep-learning library developed at Google. It makes the building of deep learning models easy and intuitive through the use of Keras as its high-level API. 

Computer vision tools - tensorflow

Some of the networks that can be built using TensorFlow include:

  • Convolutional neural networks 
  • Fully Connected Networks
  • Recurrent neural networks 
  • Long Short Term Memory networks 
  • Generative Adversarial Networks

TensorFlow is quite popular among developers because it’s easy to use, and gives you multiple tools for performing various actions. Some of the tools in the ecosystem include: 

  • TensorBoard for visualizing and debugging models 
  • TensorFlow Playground for tinkering with neural networks on a browser 
  • TensorFlow Hub that contains numerous trained computer vision models
  • TensorFlow Graphics, a library for working with graphics 

We have already mentioned that convolutional neural networks(CNN) are majorly used in computer vision tasks. In as much as you can use the normal artificial neural networks, CNNs have proven to perform better. 

Let’s look at a code snippet for building a simple neural network. In this snippet you can see that: 

  • A network of layers is initialized using the `Sequential` function from Keras 
  • `Conv2D` defines the convolutional layers with a 3 by 3 feature detector. The feature detector reduces the size of the image while maintaining important features
  • `MaxPooling2D` does pooling. The features obtained above are passed through a pooling layer. Common types of pooling include max pooling and min pooling. Pooling ensures that the network is able to detect an object in an image irrespective of its location in the image
  • The convolutional and pooling layers are repeated. However, you are free to define your own network architecture. You can also use common network architectures 
  • The `Flatten` layer transforms the output of the pooling layer to a single column that can be passed to a fully connected layer 
  • `Dense` is that fully connected layer. In this layer, an activation function corresponding to the type of problem is applied
  • The last layer is responsible for producing the final output of the network
model = tf.keras.Sequential(
    tf.keras.layers.Conv2D(32, (3,3), activation="relu",input_shape=(32, 32, 3)),
    tf.keras.layers.MaxPooling2D((2, 2), strides=2),

    tf.keras.layers.Conv2D(64, (3,3), activation="relu"),
    tf.keras.layers.MaxPooling2D((2, 2), strides=2),

    tf.keras.layers.Dense(100, activation="relu"),
    tf.keras.layers.Dense(10, activation="softmax")

When building a network like the one above, you can use Neptune to track the experiment. This is important so that your experiment is reproducible. It would be very unfortunate to spend days training a network whose performance you can not reproduce later. 

The TensorFlow and Neptune integration lets you:

  • Log model hyperparameters on every run 
  • Visualize the model’s learning curves 
  • See the hardware consumption for every run 
  • Log model weights 
  • Log model artifacts, such as images and the model itself

PyTorch is an open-source deep learning library based on the Torch library. It also supports distributed training as well as serving your computer vision models. 

Computer vision tools - pytorch

Other PyTorch features include: 

  • Deployment on mobile devices 
  • Support for ONNX
  • C++ front-end 
  • Supported on major cloud platforms 
  • A rich ecosystem of tools and libraries 

The PyTorch and its ecosystem are also supported by the Neptune machine learning experimentation platform. This PyTorch + Neptune integration lets you: 

  • Log torch tensors 
  • Visualize model loss and metrics 
  • Log torch tensors as images 
  • Log training code 
  • Log model weights 

Defining a convolutional neural network is quite similar to the TensorFlow definition with a few cosmetic changes. As you can see, you still have to define convolutional and pooling layers as well as indicate activation functions. 

import torch.nn as nn
import torch.nn.functional as F
class Net(nn.Module):
    def __init__(self):
        self.conv1 = nn.Conv2d(3, 6, 5)
        self.pool = nn.MaxPool2d(2, 2)
        self.conv2 = nn.Conv2d(6, 16, 5)
        self.fc1 = nn.Linear(16 * 5 * 5, 120)
        self.fc2 = nn.Linear(120, 84)
        self.fc3 = nn.Linear(84, 10)

    def forward(self, x):
        x = self.pool(F.relu(self.conv1(x)))
        x = self.pool(F.relu(self.conv2(x)))
        x = x.view(-1, 16 * 5 * 5)
        x = F.relu(self.fc1(x))
        x = F.relu(self.fc2(x))
        x = self.fc3(x)
        return x
net = Net()

If you don’t like writing networks in raw PyTorch code, you can use one of its high-level API libraries. One such package is the `fastai` library. 


Fastai is a deep learning library that is built on top of PyTorch. 

Computer vision tools - fastai

Some of the features of the library include: 

  • A computer vision module that is GPU optimized 
  • A two-way callback system that has access to any part of the data
  • Easy to get started with when coming from other libraries
  • Supports cyclical learning rates

Fastai metrics can also be logged to Neptune. The integration also lets you monitor and visualize your model’s training process. 

Let’s look at an example of using Fastai for image classification. The first step is usually to create a `Learner`. A `Learner` combines a model, a data loader, and a loss function. While defining a `Learner` you can use a pre-trained model and fine-tune it on your dataset. This referred to as transfer learning and will usually result in better model performance compared to training a model from scratch. Pre-trained models are usually hard to beat because they trained on millions of images which are hard to obtain for an individual. Furthermore, a lot of computational resources are required to train a model with millions of images.

from import *
dls = ImageDataLoaders.from_name_func(path, files, label_func, item_tfms=Resize(224))
learn = cnn_learner(dls, resnet34, metrics=error_rate)

You can then use this `Learner` to run predictions. 


Fastai also provides tools for downloading sample data and augmenting images.

Check how you can leverage Neptune to log and track fastai metrics.

    n.relu1 = L.ReLU(n.fc1, in_place=True)
    n.score = L.InnerProduct(n.relu1, num_output=10, weight_filler=dict(type='xavier'))
    n.loss =  L.SoftmaxWithLoss(n.score, n.label)
