h2. Project Overview
*Issue:* When two projectors cast images onto the same flat screen, the overlapping portion becomes brighter than the surrounding area, causing uneven illumination).
*Method:* Identify where the projections intersect and generate smoothly varying alpha masks so that each projector’s contribution transitions gradually across the shared zone)
*Output:* A lightweight, reproducible prototype using Python and OpenCV that demonstrates the blending behavior on static images).
---
h2. Objectives
* Clarify the problem and choose an achievable solution strategy before starting development.
* Build an alpha-blending workflow and refine it until the overlap becomes visually uniform from a standard viewing distance.
* Test the approach using a controlled set of images, documenting parameters and results to ensure the experiment can be repeated.
*Success metric: the blended region should show no noticeable edge or brightness jump.
---
h2. Scope & Operating Assumptions
* *System setup:* two projectors aligned toward a flat projection surface, with their optical axes roughly perpendicular to the screen.
* *Content type:* initial work focuses on still images, with possible extension to video later.
* *Overlap shape:* treated as a roughly rectangular band where the blending weights decrease linearly from one projector to the other.
* *Calibration approach:* prioritize simple, consistent procedures, introducing further correction only if visible imperfections remain.
