Transport of Event Equation: Phase Retrieval from Defocus Events
Kaito Hori, Chihiro Tsutake, Keita Takahashi +1
To time-efficiently and stably acquire the intensity information for phase retrieval under a coherent illumination, we leverage an event-based vision sensor (EVS) that can detect c…
Events Meet Phase-Shifting Digital Holography: Practical Acquisition, Theory, and Algorithms
Ittetsu Uchiyama, Chihiro Tsutake, Keita Takahashi +1
We introduce a novel phase-shifting digital holography (PSDH) method leveraging a hybrid event-based vision sensor (EVS). The key idea of our method is the phase shift during a sin…
Fast Sign Retrieval via Sub-band Convolution: An Elementary Extension of Binary Classification
Fuma Ito, Chihiro Tsutake, Keita Takahashi +1
To efficiently compress the sign information of images, we address a sign retrieval problem for the block-wise discrete cosine transformation (DCT): reconstruction of the signs of…
