Cats vs Dogs : Image Classification using CNN
Introduction
Cat and Dog Classification using CNN (Convolutional Neural Network) for image classification it is one of the most popular deep learning projects. It trains a neural network model to automatically recognize whether image contains a dog or cat. In artificial intelligence, Image classification has become an important application. because it helps system to understand visual data efficiently.
In this project how CNN architecture can learn image features automatically without manually extracting them.
What is CNN?
A Convolutional Neural Network (CNN) is a deep learning algorithm mainly designed for image processing tasks. CNN model automatically identifies patterns such as shapes, edges, textures and object from images.
CNN mainly consists of:
- – Pooling Layers
- – Convolution Layers
- – Output Layer
- – Activation Functions
- – Fully Connected Layers
For Image Recognition tasks, CNN provides better accuracy than other traditional machine learning techniques
