Drawbacks of widespread stereo matching techniques
DANIEL PAZ
Obtaining a depth map is not a easy task, as for the past 30 years a wide array of methods has been developed, with varied results. In this blog, those methods will be discussed.
The WFPI technique applied in ophthalmology
CAROLINA BELDA
The study of the ocular aberrations is an important field concerned in ophthalmology due to the great amount of visual quality information that we can obtain from it.
The optics of the human eye at 8.6 µm resolution
T·EYEDE TEAM
In this work, we characterize the in vivo ocular optics of the human eye with a lateral resolution of 8.6 microns, which implies roughly 1 million measurement points for a pupil diameter of 9 mm.
Inverse multiscale discrete radon transform by filtered backprojection
WOOPTIX TEAM
The Radon transform is a valuable tool in inverse problems such as the ones present in electromagnetic imaging.
Wave Front Phase Imaging (WFPI) applied to wafer geometry
JAN OLAF GAUDESTAD
WFPI is based on registering the intensity distribution at two different optical planes using two conventional imaging sensors while acquiring two images with the exact same field of view.
Light Field: a VFX life changer
JAVIER GONZALEZ
Light-field imaging is an imaging technology that produces images conceivable to alter the focus in an existing picture. Contradicted to conventional pictures, all the ranges in an image shot with a light field camera can be focused to create a specific detail more honed or any portion of an obvious region.
VR Applications
JAVIER MARTIN
We have talked about XR and the reality-virtuality continuum, so now that we already know VR, it is the turn for “what can we do in VR?”. From XR to VR. Light field projections could be a solution.
Wooptix and poLight Release SDK to Bring Light Field Capture to Consumers
Light field technology developer Wooptix® is partnering with optical component developer poLight® to enable a significant advancement in the capabilities of light field-based camera systems suitable for portable device such as smartphones, laptops, tablets, wearables and more.
Advantages of light field images in social media
SANTIAGO BASALLO
Before talking about the advantages of light field images applied to social networks, I would like to specify a little what is understood by light field (LF) image from my graphic designer point of view.
Advances in ophthalmology through WFPI
T·EYEDE TEAM
Ocular optics is normally estimated based on 2,600 measurement points within the pupil of the eye, which implies a lateral resolution of approximately 175 microns for a 9 mm pupil diameter.
