I am looking for visual stimuli that produce a similar effect than the well know “Dalmatian dog illusion” (see Figure attached).
If you look briefly at the Dalmatian dog illusion for the first time, it looks like a pattern of meaningless black and white stains (left panel). However, once a priming cue is briefly presented (the red contour in the right panel) the representation of a Dalmatian dog in a field becomes apparent. Once “seen” this representation will remain apparent even after the priming cue is removed and can't be unseen (look at the left panel again without the red contour).
Do you know other types of visual stimuli containing a hidden object shape that never pops-out before and always pops-out after the transient presentation of a priming stimulus?
Thank you!
Not a visual stimulus, but the same phenomenon can also be found in auditon with vocoded speech.
E.g., try the 'sentences' on this page, with 10 noise channels before and after listening to the "Clear Speech":

Freaky!
Pete R Jones Thank you Pete this is interesting
Fiona Macpherson Thank you Fiona this is very relevant!
Here is a similar one, which you will never be able to not see it again once you've found it:

Similar to the cigar but a harder one. It resets for me, I unsee it. Every time I visit it I see a pig-ish animal first. Once I use a cue though (the cue that works for me is imagine the photo as rotated to the right), I can see the dog.

Also, though a bistable stimulus, a Necker cube can be controlled by a priming cue if either the front or back side is highlighted.
