Two optical switches were integrated on a single LiNbO(3) substrate to construct an array. Two switches were connected by a thin film waveguide in such a way that one of the outputs of the first switch leads to the entrance of the second switch. As an array, one input of the first switch fans out to three outputs controlled by an electrical signal. When no(More)
ABSTRACT This paper proposes a no-reference type SSIM estimation method applied to compressed image sequences. The proposal transforms the SSIM formula into a form without reference signals (i.e. original images), which consists of two parameters to be estimated from the bitstream. One is quantization error variance contributing to existing noreference PSNR(More)
