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.
