-### Automatic rotation detection
+---
-
-The rotation‑estimation method is based on analyzing the distribution of gradient orientations within 
-a video frame. After converting the frame to grayscale, the algorithm computes horizontal and vertical 
-image gradients using Sobel operators and derives per‑pixel gradient magnitudes and orientations. 
-These orientations are folded into the range [0, 180) and accumulated into a fixed‑size, 
-magnitude‑weighted histogram. The histogram represents the structural edge distribution of the frame, 
-independent of brightness fluctuations or local lighting artifacts. By comparing the total gradient
-energy concentrated near 0 degrees (vertical edges) with the energy near 90 degrees (horizontal edges), 
-the method determines whether the frame is more consistent with an upright or sideways orientation.
-
-This approach is designed for environments where brightness‑based cues are unreliable, such as
-live concerts with strobe lights, LED walls, haze, and crowd movement. It relies solely on geometric 
-edge structure, which remains stable even under extreme lighting variation. The implementation is 
-optimized for high‑throughput video processing: all intermediate Mats, buffers, and histograms are 
-preallocated, and pixel data is accessed directly through pointers to avoid per‑frame memory 
-allocation. The method is intentionally biased toward the upright orientation, returning a sideways
-classification only when the horizontal‑edge energy significantly exceeds the vertical‑edge energy.
