Image Enhancement v8.0 IP

I am using Image Enhancement (8.0) ip core on Vivado 15.2. I noticed that changing the parameters on GUI doesn't have any effect on the output video. Is this a known issue? I couldn't find this issue addressed anywhere. How can I change the parameters?

Re: Image Enhancement v8.0 IP

HI @Anonymous

The parameters NOISE_THRESHOLD, ENHANCE_STRENGTH and HALO_SUPPRESS are to be set to values with in the limits mentioned in PG003.
The core GUI will allow you to set values outside these ranges. (Known issue AR61998). But it will not take any efftect.

SO please ensure that you specif the CORE GUI paramet within the range mentioned in the table in page 20 of PG003.

Hello @nagabhar @balkris

 

I have set values within that range itself. Enhance strength 0.125 (default) and 1 ...... the output video looks same.

Re: Image Enhancement v8.0 IP

HI @Anonymous

 

The difference between Enhance strength values of 0 , 0.125 and 1  might be negligible if the input image pattern already has sharp edges.
can you just show the input image pattern and output image patterns for the respective strength values?

Thanks
