Image Classification using TensorFlow: A Beginner’s Guide
Image classification is one of the most important problems in computer vision. It is a process of assigning a label to an image based on its contents. This label can be anything, such as the object in the image, the scene, the texture, etc.
TensorFlow is an open-source machine-learning platform that can be used for image classification. It is a library that is used for a variety of tasks, such as classification, recognition, and prediction.
In this article, we will be using TensorFlow to build an image classifier. We will be using a dataset of images that have been labelled with various object categories. The goal of this article is to show you how to build an image classifier using TensorFlow.
What is TensorFlow?
TensorFlow is a popular open-source software library for doing data analysis and machine learning. It was originally developed by Google Brain and is now used by many major tech companies, including Uber, Airbnb, and Twitter. TensorFlow is used for a variety of tasks, including image classification, natural language processing, and time series analysis.
If you’re new to TensorFlow, or if you’re just looking for a quick introduction to the basics, this article is for you. We’ll give you a brief overview of what TensorFlow is and how it works, as well as some of the common applications of the software.
How can TensorFlow be used for image classification?
TensorFlow is a powerful tool that can be used for a variety of tasks such as identifying objects in images or labelling images for content.
TensorFlow can be used for image classification in a few different ways:
- One way is to use a pre-trained model that has already been trained on a large dataset. This approach is often used when you want to quickly get started with image classification and don’t have the time or resources to train your own model.
- Another way to use TensorFlow for image classification is to train your own model. This approach requires more time and resources, but it also allows you to create a custom model that is tailored to your specific needs.
What are the benefits of using TensorFlow for image classification?
-
Open-source platform: Firebase provides a real-time database that can synchronize between many clients in real time, making it perfect for developing real-time applications such as chat apps and live streaming.
-
Data visualization: TensorFlow provides a better way of visualizing data with its graphical approach. It also allows easy debugging of nodes with the help of Tensor Board. This reduces the effort of visiting the whole code and effectively resolves the neural network.
-
Scalable: Almost every operation can be performed using this platform. Its characteristic of being deployed on every machine and graphical representation of a model allows its users to develop any kind of system using TensorFlow.
Hence TensorFlow has been able to develop systems like Airbnb, Dropbox, Intel, Snapchat, etc.
-
Compatible: It is compatible with many languages such as C++, JavaScript, Python, C#, Ruby, and Swift. This allows a user to work in an environment they are comfortable in.
-
Parallelism: TensorFlow finds its use as a hardware acceleration library due to the parallelism of work models. It uses different distribution strategies in GPU and CPU systems.
A user can choose to run its code on either of the architecture based on the modelling rule. A system chooses a GPU if not specified. This process reduces memory allocation to an extent.
Steps to get started with TensorFlow for image classification
Following are the steps to get started with TensorFlow for image classification:
- Examine and understand the data
- Build an input pipeline
- Build the model
- Train the model
- Test the model
- Improve the model and repeat the process
The below tutorial shows how to classify images of flowers using a tf.keras.Sequential model and load data using tf.keras.utils.image_dataset_from_directory.
