The core idea of perceptual hashing is to scale video frames to a fixed size (e.g., 8×8 pixels), convert them to grayscale, compute DCT (Discrete Cosine Transform) coefficients, and generate a 64-bit binary fingerprint.

UnverifiedThe core algorithm of JPEG image compression is the Discrete Cosine Transform (DCT); images are divided into 8×8 pixel blocks, and after each block undergoes a frequency-domain transform, high-frequency detail information is selectively discarded.71% similarUnverifiedSenseTime is reportedly developing a multimodal image large model called U1 Pro, internally benchmarked against GPT Image 2, targeting design scenarios, supporting long-range generative review loops, and capable of outputting at up to 8K resolution.68% similarUnverifiedVideo super-resolution technology relies on deep convolutional neural networks to perform pixel-level reconstruction of low-resolution frames, using inter-frame temporal information to fill in motion details, which reduces flickering and artifacts compared to single-frame image upscaling.68% similarVerifiedGenerating an 8-second, 24-fps video means the model must maintain semantic consistency across 192 frames simultaneously on the time axis, with a computational load approximately tens of times greater than that of a single image at the same resolution.67% similar
