DHash 如何工作

public class KeyframeDeduplicationService
{
    // dHash parameters: 9x8 grayscale = 64 bits
    private const int HashWidth = 9;
    private const int HashHeight = 8;
    private const int DefaultHammingThreshold = 10;

    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)
  Frame 2: hash=0x8f3a2c1f → SKIP (distance=2 from frame 0)

public class BatchClipEmbeddingService

    private const int DefaultBatchSize = 8; // 8 images per GPU pass

    public async Task<Dictionary<int, float[]>> GenerateBatchEmbeddingsAsync(
        Dictionary<int, string> framePaths,
        int batchSize = DefaultBatchSize,

        var session = await GetOrLoadClipModelAsync(ct);
        var results = new Dictionary<int, float[]>();

        // Pre-index batch for O(1) lookup (not batch.IndexOf!)
        var batches = framePaths
            .Select((kvp, idx) => (idx, kvp.Key, kvp.Value))
            .Chunk(batchSize);

        foreach (var batch in batches)
        {
            // Create batch tensor [batchSize, 3, 224, 224]
            var tensor = new DenseTensor<float>(new[] { batch.Length, 3, ClipImageSize, ClipImageSize });

            // Preprocess images in parallel (simplified; production uses vectorised span copy)
            Parallel.ForEach(batch, item =>
            {
                var (batchIdx, frameIndex, path) = item;
                var localIdx = batchIdx % batchSize;
                PreprocessImageToTensor(path, tensor, localIdx); // ImageSharp pixel buffers
            });

            // Single GPU pass for entire batch
            var inputs = new List<NamedOnnxValue>
            {
                NamedOnnxValue.CreateFromTensor("input", tensor)
            };

            using var outputResults = session.Run(inputs);
            // Extract embeddings from batch output...
        }

        return results;
    }
}

性能比较:*

Input: 30 keyframes (after deduplication)

Serial processing (1 frame at a time):
  30 × 200ms = 6,000ms (6.0 seconds)

Batch processing (8 frames per pass):
  4 batches × 350ms = 1,400ms (1.4 seconds)

Speedup: 4.3x

  • 批次电压 [8, 3, 224, 224] 使用与单个图像相同的 GPU 内存 *% 1
  • 运行时间优化内部的批量作业

关键创新

  1. 近邻内嵌入式孕育“: ” 只有“~2% 」 有直接CLIP嵌入的 CLIP}. 新的方法通过时间接近重量,在“MS K3 秒内将嵌入附近的镜头。

  2. 标定语义窗口: 建構10- 第二個單字視窗, 透過 Jaccar 低廉的語言流動代理 *(low 重複 MS K3 主题變更).BMZK5當可用時可以使用或嵌入漂移

  3. 认识切剪类型@:_Fade-to-_Black and unformissions 强力表示场景边界@,}提升边界评分=.{

  4. 适应性推进权“:”不是固定的阈值,而是从“25%”和“(”中分数的顶端选择边界。

  5. 时间制约因素“:”强制实施最小的“15”场景和部队边界(在 @5-”)

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%
