FFBsPCA principal radial functions in Fourier domain. The dataset contains n = 105 simulated human mitochondrial large ribosomal subunit projection images corrupted by additive white Gaussian noise with SNR= 1/30. Image size is 240 × 240 pixels, R = 98, c = 0.196. Each radial function is labeled with angular index k, radial order l, and eigenvalue λ.
