Abstract :
Super Resolution (SR) is an interesting topic in video and image research. Super resolution image reconstruction (SRR) is one of the commonest SR technologies and has been proposed in many forms. SRR reconstructs a highresolution image from multiple low-resolution images. However, the low-resolution images require an aliasing process prior to reconstruction. The present paper analyzes SRR in the frequency domain, and demonstrates that SRR is unsuitable for general applications.
