Grayscale Image Conversion

A serverless image processing service that converts color images to grayscale using AWS infrastructure.

Overview

This project implements an image conversion service deployed on AWS, leveraging serverless architecture for scalability and cost-efficiency.

Architecture

• AWS Lambda: Hosts the grayscale conversion function
• Amazon S3: Stores input and output images
• API Gateway: Provides HTTP endpoint for image upload
• Additional AWS Services: IAM for permissions, CloudWatch for monitoring

Features

• Convert color images to grayscale (PNG format)
• Serverless architecture for automatic scaling
• Load testing with Locust for performance validation

Files

• grayscale_converter.py - Core image conversion logic using PIL
• locust_grayscale_benchtest.py - Load testing script

Usage

Upload an image to the API endpoint:

POST /convert-to-grayscale
Content-Type: multipart/form-data

The service returns a grayscale version of the uploaded image.

Requirements

• Python 3.x
• PIL/Pillow
• Locust (for testing)

Deployment

Deployed as an AWS Lambda function with S3 integration for image storage and API Gateway for HTTP access.
