    • TouchPoint: A Wrist-Worn, On-Body Touch Interaction Device 

      Chatterjee, Ishan
      The small size of touchscreens on smartwatches makes interaction cumbersome, motivating the need for touch interaction beyond the perimeter of a wrist-worn device. This thesis presents TouchPoint, a wrist-worn sensor device ...

    • Toward Shape from a Single Specular Flow 

      Vasilyev, Yuriy; Zickler, Todd; Gortler, Steven J.; Ben-Shahar, Ohad (2011)
      In “Shape From Specular Flow: Is One Flow Enough?” (Vasilyev, et al., 2011 [5]) we show that mirror shape can often be reconstructed from the observation of a single specular flow. In this technical report we provide ...

    • Unique specular shape from two specular flows 

      Canas, Guillermo D.; Vasilyev, Yuriy; Adato, Yair; Zickler, Todd; Gortler, Steven J.; Ben-Shahar, Ohad (2009)
      When a curved mirror-like surface moves relative to its environment, it induces a motion field—or specular flow—on the image plane that observes it. This specular flow is related to the mirror’s shape through a non-linear ...

    • The von Kries hypothesis and a basis for color constancy 

      Chong, Hamilton; Gortler, Steven; Zickler, Todd (Institute of Electrical and Electronics Engineers (IEEE), 2007)
      Color constancy is almost exclusively modeled with diagonal transforms. However, the choice of basis under which diagonal transforms are taken is traditionally ad hoc. Attempts to remedy the situation have been hindered ...

    • What Do Color Changes Reveal About an Outdoor Scene? 

      Sunkavalli, Kalyan Krishna; Romeiro, Fabiano Segadaes; Matusik, Wojciech; Zickler, Todd; Pfister, Hanspeter (Institute of Electrical and Electronics Engineers, 2008)
      In an extended image sequence of an outdoor scene, one observes changes in color induced by variations in the spectral composition of daylight. This paper proposes a model for these temporal color changes and explores its ...
