Why the output of "Retina Magno" changed consistently when applying retina to a single picture
I have tried to apply retina to a single picture with default parameters. As the cycle index being increased, the output of "Retina Magno" changed consistently and at last the output was a black image. I want to know why that happens. So I read the article "Using Human Visual System modeling for bio-inspired low level image processing" and find this .
But the question still puzzle me. Could you give me some directions?
my second question:
Please look at this .
OPL transfer function is shown in Fig4b. With the time goes by, I think the frequency tend to zero. And I think the FOPL is similar with the parvo output according to Fig11a. But the magno output not the parvo output become zero in the end! Could you tell me where the problems are? Maybe I misunderstood the author's intentions.
what do you mean: cycle index ? (is there any code ?)
imho, picture b shows an input on the left side(with a cyclic grayscale ramp) and the parvo output img on the right
Thanks for your reply!
was it about the image above ? (i wasn't sure)
The code is as follows.
With the cycle index being increased, the output of "Retina Magno" changed consistently and at last the output was a black image.
so, completely different, from what i thought ;)
well i tried, and i can side your findings more or less..
(well, it gets darker here, but not totally black)
it's one of those things, where you probably might want to ask the author for an explanation ?)
I just try to apply the retina to a single image.
The image I tested is a tank model that is on the desk. In the fifth loop, there is only a tank in the retinaOutput_magno. However, in the tenth loop, both the tank and the background appear in the retinaOutput_magno. I am intresting in the specific order in which different objects appear or disappear in the magno output. What factors affect the order?
just to clarify: the parvo img stays constant, right ?
As I observed, the parvo img is dynamic.
I added a new question ;)
