 h2. Project Overview 

 *Problem:* Two projectors produce overlapping images on a planar screen, creating luminance non‑uniformity (the shared region appears brighter). 
 *Approach:* Detect the overlap and apply spatially smooth alpha‑blending masks whose weights vary linearly from 1 to 0 across the overlap band. 
 *Deliverable:* A minimal, reproducible still‑image prototype implemented in Python (OpenCV). 

 --- 

 h2. Objectives 

 * Define the problem and select a feasible solution path prior to implementation. 
 * Implement an alpha‑blending pipeline and iterate until seams are not perceptible at normal viewing distance. 
 * Validate the method with a small set of test images, recording inputs, parameters, and outcomes to ensure reproducibility. 

 *Success criterion:* no visible seam or luminance discontinuity in the overlap region.

 h2. Scope & Operating Assumptions 

 * *Configuration:* two projectors and a planar screen; projector optical axes nominally normal (perpendicular) to the screen. 
 * *Media:* still images for the initial phase (video may follow). 
 * *Overlap geometry:* approximately rectangular; blend weights vary linearly from 1 to 0 across the overlap. 
 * *Calibration philosophy:* favor simple, reproducible steps; apply additional calibration only if visible artifacts persist.
