Certain aspects of the present disclosure provide a system for processing image data from an intraoperative diagnostic device in real-time during an ophthalmic procedure. The system comprises an image capture element that captures a grayscale image of a first size and an image processing element that scales the grayscale image from the first size to a second size. The system also comprises a two-stage classification model comprising: a feature extraction stage to process the scaled grayscale image and generate a feature vector based on the scaled grayscale image and a classification stage to process the feature vector and generate an output vector. The image processing element is further configured to determine an image quality of the obtained grayscale image based on the output vector for display to an operator and the image quality of the obtained grayscale image indicates a probability that the obtained grayscale image includes an artifact.

Real-time detection of artifacts in ophthalmic images

Techniques are disclosed for systems and methods to provide improved ocular aberrometry. An ocular aberrometry system includes a wavefront sensor configured to provide wavefront sensor data associated with an optical target monitored by the ocular aberrometry system and a logic device configured to communicate with the wavefront sensor. The logic device is configured to receive ocular aberrometry output data including at least the wavefront sensor data provided by the wavefront sensor, determine estimated ocular alignment deviations corresponding to a relative position and/or orientation of the optical target monitored by the ocular aberrometry system based, at least in part, on the received ocular aberrometry output data, and generate user feedback corresponding to the received ocular aberrometry output data based, at least in part, on the estimated ocular alignment deviations.

Ocular aberrometer systems and methods

Techniques are disclosed for systems and methods to provide dry eye and/or tear film hydration monitoring in the context of ocular aberrometry. An ocular aberrometry system includes a wavefront sensor configured to provide wavefront sensor data associated with an optical target monitored by the ocular aberrometry system and a logic device configured to communicate with the wavefront sensor. The logic device is configured to receive ocular aberrometry output data including at least the wavefront sensor data provided by the wavefront sensor, determine a tear film hydration state associated with the optical target based, at least in part, on the received ocular aberrometry output data, and generate user feedback corresponding to the determined tear film hydration state based, at least in part, on the received aberrometry output data and/or the determined tear film hydration state.

Dry eye mitigation for ocular aberrometry systems and methods

Techniques are disclosed for systems and methods to provide improved ocular aberrometry recovery. An ocular aberrometry system includes a wavefront sensor configured to provide wavefront sensor data associated with an optical target monitored by the ocular aberrometry system and a logic device configured to communicate with the wavefront sensor. The logic device is configured to receive ocular aberrometry output data including at least the wavefront sensor data provided by the wavefront sensor, identify imaging artifact induced singularities in the received ocular aberrometry output data, determine corrected aberrometry output data based, at least in part, on the identified singularities and the received ocular aberrometry output data, and generate user feedback corresponding to the received ocular aberrometry output data based, at least in part, on the corrected aberrometry output data.

Ocular aberrometry recovery systems and methods

An imaging system is configured to capture images of both obverse and reverse sides of a collectible item using a single image captured by a single camera. The reflective faces of two flat mirrors are positioned at a 90-degree angle, and a collectible item is positioned and secured between the mirrors such that parallel faces of the item or its case are oriented at a 45-degree angle between the flat mirrors. A camera is mounted to face the mirrors with its perspective being parallel to the faces of the item, looking into the mirrors. The camera can see mirrored reflections of both faces of the item simultaneously from a single perspective and can capture views of both faces in a single camera image. The single image can then be cropped and reverse-mirrored automatically or manually in software to extract images of the obverse and reverse sides of the item.

Simultaneous single obverse and reverse imaging of collectible items

Techniques are disclosed for systems and methods to provide improved ocular aberrometry. An ocular aberrometry system includes a wavefront sensor configured to provide wavefront sensor data associated with an optical target monitored by the ocular aberrometry system and a logic device configured to communicate with the wavefront sensor. The logic device is configured to determine a complex analysis engine for the ocular aberrometry system based, at least in part, on an aberrometer model and/or an eye model associated with the ocular aberrometry system, wherein the aberrometer model and the eye model are based, at least in part, on wavefront sensor data provided by the wavefront sensor. The logic device is also configured to generate a compact analysis engine for the ocular aberrometry system based, at least in part, on the determined complex analysis engine.

Ocular aberrometer characterization systems and methods

A method to interactively convert a source language video/audio stream into one or more target languages in high definition video format using a computer. The spoken words in the converted language are synchronized with synthesized movements of a rendered mouth. Original audio and video streams from pre-recorded or live sermons are synthesized into another language with the original emotional and tonal characteristics. The original sermon could be in any language and be translated into any other language. The mouth and jaw are digitally rendered with viseme and phoneme morphing targets that are pre-generated for lip synching with the synthesized target language audio. Each video image frame has the simulated lips and jaw inserted over the original. The new audio and video image then encoded and uploaded for internee viewing or recording to a storage medium.

Method of translating and synthesizing a foreign language

An ophthalmic apparatus for precisely positioning an optical instrument, such as a wavefront aberrometer, in three dimensions with respect to a patient's eye. The ophthalmic apparatus may include an optical instrument directed in a first direction toward a target area to receive light therefrom and a camera directed in a second direction toward the target area to receive light therefrom, the first and second directions being non-parallel. The camera may include imaging optics to form an optical image on a photodetector array using light reflected from the target area. The ophthalmic apparatus may also include a processor configured to correlate a position of the optical image on the photodetector array with the distance between the optical instrument and the target area.

Optical instrument alignment system

A system and method for determining an objective quality metric for image data collected by a wavefront aberrometer. The method may include quantifying a plurality of characteristics of the image data and calculating the objective quality metric based on the quantified characteristics of the image data. The objective quality metric can be a weighted sum of the quantified characteristics of the image data. The weightings for the weighted sum can be determined based on subjective quality metrics assigned to a set of training image data by a human expert.
