I am doing a project in image compression based on space filling curves. For the performance evaluation of this project I was calculated performance metrics such as MSE, PSNR, SSIM, NCCR, COC. In this the *PSNR value exceeds 90* , whether it is correct or not?

No, you can not get PSNR 90dB. If your image is 8 bit, maximum value of PSNR should be around 64dB if your algorithm is performing so well.
