Title: Gershi Koltun: Innovator in Depth Measurement and Content Authentication
Introduction
Gershi Koltun is a notable inventor based in Givat Ada, Israel. He has made significant contributions to the fields of depth measurement and digital content authentication. With a total of 4 patents to his name, Koltun continues to push the boundaries of technology through his innovative ideas.
Latest Patents
Koltun's latest patents include a method for time-of-flight depth measurement using modulation frequency adjustment. In this method, a scene is illuminated using a time-of-flight (ToF) light source modulated at a first modulation frequency F. While the light is modulated using F, depths are measured to respective surface points within the scene, represented by a plurality of respective pixels. At least one statistical distribution parameter is computed for the depths, and a second modulation frequency higher than F is determined based on this parameter. The depths are then re-measured using F to achieve a higher depth accuracy.
Another significant patent is for robust selective image, video, and audio content authentication. This method involves acquiring content data using a sensor and generating compressed reference data from the acquired content. A hash of the compressed reference data is created using a hashing function, which is then signed using an encryption function. The acquired content data is transmitted along with the compressed reference data and the signed hash, ensuring the integrity of the digital content.
