We propose a novel spectral generative model for image synthesis that departs radically from the common variational, adversarial, and diffusion paradigms. In our approach, images, after being flattened into one-dimensional signals, are reconstructed as linear combinations of a set of learned spectral basis functions, where each basis is explicitly parameterized in terms of frequency, phase, and amplitude. The model jointly learns a global spectral dictionary with time-varying modulations and per-image mixing coefficients that quantify the contributions of each spectral component. Subsequently, a simple probabilistic model is fitted to these mixing coefficients, enabling the deterministic generation of new images by sampling from the latent space. This framework leverages deterministic dictionary learning, offering a highly interpretable and physically meaningful representation compared to methods relying on stochastic inference or adversarial training. Moreover, the incorporation of frequency-domain loss functions, computed via the short-time Fourier transform (STFT), ensures that the synthesized images capture both global structure and fine-grained spectral details, such as texture and edge information. Experimental evaluations on the CIFAR-10 benchmark demonstrate that our approach not only achieves competitive performance in terms of reconstruction quality and perceptual fidelity but also offers improved training stability and computational efficiency. This new type of generative model opens up promising avenues for controlled synthesis, as the learned spectral dictionary affords a direct handle on the intrinsic frequency content of the images, thus providing enhanced interpretability and potential for novel applications in image manipulation and analysis.
