Praying mantises use 3D perception, scientifically known as
stereopsis, for hunting.
Dr Rosner, research associate in the Institute of Neuroscience at Newcastle University, said: "This helps us answer how insects achieve surprisingly complex behaviour with such tiny brains, and understanding this can help us develop simpler algorithms to develop better robot and machine vision." Praying mantises use 3D perception, scientifically known as
stereopsis, for hunting.
The OPT2 (circus) slides offer the possibility to stimulate
stereopsis (see Figure 8).
All children received in ophthalmic department underwent evaluation of visual acuity, best corrected visual acuity after cycloplegic refraction, fundoscopy, assessment for squint using Hirschberg test and cover uncover test,
stereopsis testing using Titmus test and detailed anterior and posterior segment examination.
Stereopsis, or depth perception from fusing the left and right monocular vision is, however, more limited to +/-40[degrees].
Each physician underwent ophthalmologic examination and those with best corrected visual acuity of 20/20 in both eyes, sufficient
stereopsis and normal findings on slitlamp examination were included in the study.
"I guess I come from this vertebrate-biased tradition, which thought of
stereopsis as something very complicated and advanced that only 'higher organisms' can do," Read said.
Also known as "
stereopsis", 3-D or stereo vision helps humans and other creatures determine the distances to objects we see.
The role of innervational factors like convergence and divergence and that of accommodation,
stereopsis, and motor and sensory fusion in the etiopathogenesis of infantile exotropia have long been the subject of debate among ophthalmologists, and in essence, the cause of concomitant infantile XT is still unknown.
Stereopsis facilitates the precise judgment of distance, and stereoacuity is used to evaluate it.
