DCTdiff: Intriguing Properties of Image Generative Modeling in the DCT Space
ICML 2025poster
This paper explores image modeling from the frequency space and introduces DCTdiff, an end-to-end diffusion generative paradigm that efficiently models images in the discrete cosine transform (DCT) space. We investigate the design space of DCTdiff and reveal the key design factors. Experiments on di…
