Application Overview
    Application Overview
This Flask-based application is a versatile tool for image and video processing, particularly geared towards creating, manipulating, and blending images for various creative projects. The application supports multiple functionalities, including image uploads, grayscale and binary mask generation, image blending, and video frame extraction. It's designed to provide a smooth user experience for managing and processing media files within a structured web interface.

Key Features
Image Uploading and Storage:

Users can upload images in various formats (PNG, JPG, JPEG, GIF) through a user-friendly web interface.
Uploaded images are securely stored in designated directories (static/archived-images), ensuring easy access and management.
Uploaded images are automatically organized by upload time, with the most recent images displayed first.
Mask Generation:

The application allows users to create masks for images using two different methods:
Grayscale Masking: Converts an image to grayscale and uses it as a mask for blending purposes.
Binary Masking: Converts an image to a binary format by calculating the mean pixel value and using it as a threshold. The resulting binary mask can be inverted for alternative effects.
These masks are saved in the static/archived-masks directory and can be applied to other images within the application.
Image Blending:

Users can blend two images using a selected mask (either grayscale or binary) with adjustable opacity settings.
The blending process is performed using the Pillow library, and the final blended image is saved in the static/archived-store directory.
The application ensures that the dimensions of all images involved in blending are consistent by resizing them to a standard size (512x768 pixels).
Video Frame Extraction:

The application can extract random frames from a video file, enabling users to generate a series of images from their video content.
Extracted frames are saved in the static/archived-images directory for further manipulation or use in blending processes.
Image Selection and Mask Application:

Users can select images for further processing, such as applying masks or blending with other images.
The application supports a selection workflow that allows users to preview and choose their desired images and masks through an intuitive web interface.
Logging and Debugging:

The application is equipped with a robust logging system that tracks actions and errors throughout the execution. Logs are saved to a file (exp_log.txt), providing detailed insights into the application’s behavior for debugging and monitoring purposes.
Subprocess Integration:

Certain features, like refreshing images or videos, are handled by external Python scripts. These scripts are executed through subprocess calls, allowing the application to manage complex tasks without blocking the main process.
This modular approach ensures that the application remains responsive and can handle additional processing in the background.
Web Interface and Routing:

The application provides a clean and organized web interface, allowing users to navigate between different functionalities, such as uploading files, selecting images, creating masks, and viewing results.
All major actions are linked to specific routes (/upload, /blend_images, /get_video_images, etc.), making the application easy to extend and maintain.
Use Cases
Creative Projects: Ideal for artists and designers who want to experiment with image blending and masking techniques to create unique visual compositions.
Video Processing: Useful for content creators who need to extract and manipulate frames from their video files for promotional materials or other purposes.
Web-Based Media Management: Provides a centralized platform for managing, processing, and storing images and videos in a structured and organized manner.
Conclusion
This application serves as a comprehensive toolkit for image and video processing, blending artistic creativity with technical precision. Whether you are working on a digital art project, creating promotional content, or simply experimenting with visual effects, this application offers the tools and flexibility you need to bring your ideas to life. With its user-friendly interface, versatile functionalities, and robust backend processing, the application empowers users to explore new possibilities in image manipulation and content creation.
