Abstract Ocular optics is normally estimated based on up to 2,600 measurement points within the pupil of the eye, which implies a lateral resolution of approximately 175 µm for a 9 mm pupil diameter. This is because information below this resolution

We have designed, assembled, and evaluated a compact instrument capable of capturing the wavefront phase in real time, across various scenarios. Our approach simplifies the optical setup and configuration, which reduces the conventional capture and c

This work introduces a real-time full-resolution depth estimation device, which allows integral displays to be fed with a real-time light-field. The core principle of the technique is a high-speed focal stack acquisition method combined with an effic

The Radon transform is a valuable tool in inverse problems such as the ones present in electromagnetic imaging. Up to now the inversion of the multiscale discrete Radon transform has been only possible by iterative numerical methods while the continu

We propose a local bar-shaped structure detector that works in real time on high-resolution images. It is based on the Radon transform. Specifically in the muti-scale variant, which is especially fast because it works in integer mathematics and does

Stereoscopic techniques have the disadvantage of occlusions in the mismatched pixels between images. Monocular depth estimation together with semantic features is pro posed to improve the depth map at non-coincident areas.

Radon transform, and more specifically the multiscale Discrete Radon Transform, is a valuable tool to find straight structures on images. But the straight lines that DRT finds are those traversing completely the image, and hence DRT is unable to dete
