DHash 如何工作

public async Task<ulong> ComputeDHashAsync(string imagePath, CancellationToken ct)
{
using var image = Image.Load<Rgba32>(imagePath);
// Resize to 9x8 (one extra column for gradient comparison)
image.Mutate(x => x
.Resize(HashWidth, HashHeight)
.Grayscale());
ulong hash = 0;
int bit = 0;
// Compare adjacent pixels horizontally
for (int y = 0; y < HashHeight; y++)
{
for (int x = 0; x < HashWidth - 1; x++)
{
var left = image[x, y].R;
var right = image[x + 1, y].R;
// Set bit if left pixel is brighter than right
if (left > right)
{
hash |= (1UL << bit);
}
bit++;
}
}
return hash;
}
public static int HammingDistance(ulong a, ulong b) =>
BitOperations.PopCount(a ^ b);
}
示例输出:
Input: 50 keyframe candidates (from codec I-frames)
Deduplication (Hamming threshold 10):
Frame 0: hash=0x8f3a2c1d → KEEP (first frame)
Frame 1: hash=0x8f3a2c1e → SKIP (distance=1 from frame 0)

实例::
Input: 1881 shots from a 2-hour movie
39 keyframes with CLIP embeddings
2302 utterances from transcript
Boundary scoring per shot:
Shot 45-46: embedding=0.15, transcript=0.32, cut=0.0, temporal=0.0 → score=0.156
Shot 46-47: embedding=0.08, transcript=0.12, cut=0.0, temporal=0.0 → score=0.068
Shot 47-48: embedding=0.35, transcript=0.41, cut=0.2, temporal=0.05 → score=0.388 ← BOUNDARY
...
Adaptive threshold (top 25%): 0.25
Natural boundaries found: 45
Output: 47 scenes (avg 2.6 minutes per scene)
- Min scene: 15.2s
- Max scene: 298.4s
- Total coverage: 100%
Signals:
scenes.detected = true
scene.count = 47
scene.avg_duration = 156.3
scene.clustering_method = "multi_signal_weighted"
