Computing 2D CDFs on Downsampled Video Frames
@BattleAxeVR Do you compute 2d cdfs over each downsampled frame for video light?
Dilate Line Art Before Downscaling to Preserve Strokes
OpenCV で線画を縮小した時に線が消えないようにするアルゴリズムをGeminiくんに聞いたら kernel = cv . getStructuringElement(cv . MORPH_RECT, (3, 3)) # 画像を膨張させて線を太くする dilated_img = cv . dilate(src_img, kernel, iterations=1) こんな前処理を提案された。すごい
SAM‑3 Unifies Detection, Segmentation, Tracking for Real‑Time AI
🚀 Meta just released SAM‑3, the third version of the Segment Anything Model and it might be the biggest leap in image and video segmentation since the original SAM. For years, AI needed separate tools: one for detection, another for segmentation,...
