Related Work Stereoscopic and multiview 3D displays have been an active area of research for more than a century [10]
  2. A light field camera, also known as plenoptic camera, is a camera which captures information about the light field emanating from a scene; that is, the intensity of light in a scene, and also the direction that the light rays are traveling in space. This contrasts with conventional cameras, which records only light intensity. One type of light field camera uses an array of micro-lenses placed.
  3. The light field is a vector function that describes the amount of light flowing in every direction through every point in space. The space of all possible light rays is given by the five-dimensional plenoptic function, and the magnitude of each ray is given by the radiance. Michael Faraday was the first to propose (in an 1846 lecture entitled Thoughts on Ray Vibrations) that light should be.

Instead, we propose an algorithm for view synthesis from an irregular grid of sampled views that first expands each sampled view into a local light field via a multiplane image (MPI) scene representation, then renders novel views by blending adjacent local light fields Observing the various anatomical and functional information that spans many spatiotemporal scales with high resolution provides deep understandings of the fundamentals of biological systems.

Attention-based View Selection Networks for Light-field Disparity Estimation. This paper introduces a novel deep network for estimating depth maps from a light field image. For utilizing the views more effectively and reducing redundancy within views, we propose a view selection module that generates an attention map indicating the importance. Lytro Light Field Camera & Software Lytro has produced the first consumer-ready imaging product that takes advantage of light field imaging technology. This camera produces what their marketing materials refer to as living pictures, photos that allow the user to refocus the image or subtly change the perspective after the image has been. Different from traditional cameras, the light field cameras record spatial information with its angular information. Since the angular and spatial resolutions are limited due to the hardware shortage, view synthesis is required to provide arbitrary views. In this paper, we propose densely connected multiloss convolutional neural networks for light field view synthesis, called DCM-CNN. We build.

  1. In this paper, we present an efficient and robust deep learning solution for novel view synthesis of complex scenes. In our approach, a 3D scene is represented as a light field, i.e., a set of rays, each of which has a corresponding color when reaching the image plane. For efficient novel view rendering, we adopt a 4D parameterization of the light field, where each ray is characterized by a 4D.

Gives a great view of the surroundings and has no noticeable distortion Field of View. The field of view is largest on the lowest power objective. When you switch to a higher power, the field of view closes in towards the center. You will see more of an object on low power. Therefore, it is best to find an object on low power, center it, and then switch to the next higher power and repeat The diameter of the field of an optical light microscope is the field number, which is the diameter of the field view in mm measured at the intermediate image plane. The field number is typically listed on the microscope eyepiece. The microscope field of view is found with the following formula: Field of View = Field Number (FN) ÷ Objective. Dark field illumination. At a first sight, images captured using dark field illumination seem unusual to the viewer. The light shines at a shallow angle.

The article explains the basic principles of optical imaging with a single lens; many aspects can also be applied to multiple-lens systems (objectives). Terms like focusing, field of view, depth of field, image magnification and resolution, light collection efficiency and aberrations are discussed We propose a simple method based on the use of interference of the double-beam aperture to enhance both the axial resolution and field of view of light-sheet fluorescence microscopy. The double-beam aperture placed in the pupil plane generates multiple-spot intensity patterns in which the size of central lobe reduces. By scanning this intensity pattern along x-axis, the light sheet is generated

Google's research into light fields is bearing fruit with a glasses-free 3D display technology called Project Starline available at a few of its offices. Google revealed the work as part. Mirrors have been used to enable wide field-of-view (FOV) catadioptric imaging. The mapping between the incoming and reflected light rays depends non-linearly on the mirror shape and has been well-studied using caustics. We analyze this mapping using two-plane light field parameterization, which provides valuable insight into the geometric structure of reflected rays The microscopy field of view is the total visible area of the specimen plane, which is determined by the field number or the diameter of the diaphragm, and the magnification of the lens. This viewing field size is conversely affected by the magnification level of the microscope. While the best way to increase the field of view is by lowering.
