  • Xiong, Yi; Hirvonen, Juha; Kallio, Pasi (2013)
    Calibration is of great significance in the development of automatic micromanipulation systems. This paper presents a novel vision based procedure for three-dimensional (3D) calibration of micromanipulators. Two major ...
  • Kreutzer, Joose; Ylä-Outinen, Laura; Kärnä, Paula; Kaarela, Tiina; Mikkonen, Jarno; Skottman, Heli; Narkilahti, Susanna; Kallio, Pasi (2012)
    Structured poly(dimethylsiloxane) (PDMS) chambers were designed and fabricated to enhance the signaling of human embryonic stem cell (hESC) - derived neuronal networks on microelectrode array (MEA) platforms. The structured ...
  • Hemmilä, Samu; Cauich-Rodriguez, Juan V.; Kreutzer, Joose; Kallio, Pasi (2012)
    This paper describes rapid, simple, and cost-effective treatments for producing biocompatible and long-term hydrophilic polydimethylsiloxane (PDMS) surfaces identified in an experimental study investigating 39 treatments ...
  • Kreutzer, Joose; Ikonen, Liisa; Hirvonen, Juha; Pekkanen-Mattila, Mari; Aalto-Setälä, Katriina; Kallio, Pasi (2014)
    This paper introduces a compact mechanical stimulation device suitable for applications to study cellular mechanobiology. The pneumatically controlled device provides equiaxial strain for cells on a coated polydimethylsiloxane ...
  • Aflaki, Payman; Hannuksela, Miska; Hakala, Jussi; Häkkinen, Jukka; Gabbouj, Moncef (2011)
    In mixed-resolution (MR) stereoscopic video, one view is presented with a lower resolution compared with the other one; therefore, a lower bitrate, a reduced computational complexity, and a decrease in memory access bandwidth ...
  • Aflaki, Payman; Hannuksela, Miska M.; Hakala, Jussi; Häkkinen, Jukka; Gabbouj, Moncef (2011)
    A novel asymmetric stereoscopic video coding method is presented in this paper. The proposed coding method is based on uneven sample domain quantization for different views and is typically applied together with a reduction ...
  • Aflaki, Payman; Rusanovskyy, Dmytro; Utriainen, Timo; Pesonen, Emilia; Hannuksela, Miska M.; Jumisko-Pyykkö, Satu; Gabbouj, Moncef (2011)
    Depth-enhanced multiview video formats, such as the multiview video plus depth (MVD) format, enable a natural 3D visual experience which cannot be brought by traditional 2D or stereo video services. In this paper we studied ...
  • Aflaki, Payman; Rusanovskyy, Dmytro; Hannuksela, Miska; Gabbouj, Moncef (2012)
    Downsampling applied to texture views prior to encoding can increase the subjective quality of decoded video. In our study, we show that spatial resolution selection based on traditional pixel-based distortion metrics, ...
  • Aflaki, Payman; Hannuksela, Miska M.; Homayouni, Maryam; Gabbouj, Moncef (2012)
    Conventional mixed-resolution (MR) stereoscopic video where one view has full resolution (FR) and the other view has a lower resolution has shown to provide similar subjective quality compared to symmetric FR stereoscopic ...
  • Aflaki, Payman; Su, Wenyi; Joachimiak, Michal; Rusanovskyy, Dmytro; Hannuksela, Miska M.; Li, Houqiang; Gabbouj, Moncef (2013)
    The emerging MVC+D standard specifies the coding of Multiview Video plus Depth (MVD) data for enabling advanced 3D video applications. MVC+D specifications define the coding of all views of MVD at equal spatial resolution ...
  • Rantanen, Ville; Kumpulainen, Pekka; Venesvirta, Hanna; Verho, Jarmo; Spakov, Oleg; Lylykangas, Jani; Vetek, Akos; Surakka, Veikko; Lekkala, Jukka (2012)
    A wide range of applications can benefit from the measurement of facial activity. The current study presents a method that can be used to detect the movements of different parts of the face and expressions that they form. ...

    A wide range of applications can benefit from the measurement of facial activity. The current study presents a method that can be used to detect and classify the movements of different parts of the face and the expressions ...
  • Helkala, Janne; Viitanen, Timo; Kultala, Heikki; Jääskeläinen, Pekka; Takala, Jarmo; Zetterman, Tommi; Berg, Heikki (2014-07-14)
    The SRAM memories used for embedded micro-processor devices consume a large portion of the system's power. The power dissipation of the instruction memory can be limited by using code compression methods, which may require ...
  • Rantanen, Ville; Verho, Jarmo; Lekkala, Jukka; Tuisku, Outi; Surakka, Veikko; Vanhala, Toni (2012)
    The effect of facial behaviour on gaze tracking accuracy was studied while using a prototype system that integrated head-mounted, video-based gaze tracking and a capacitive facial movement detection for respective pointing ...
  • Rantanen, Ville; Venesvirta, Hanna; Spakov, Oleg; Verho, Jarmo; Vetek, Akos; Surakka, Veikko; Lekkala, Jukka (2013)
    The measurement of the intensity of facial muscle activity can be used in several applications such as human–computer interaction and behavioural science. A new method for the intensity measurement is presented. It is based ...

    A light-weight, wearable, wireless gaze tracker with integrated selection command source for human–computer interaction is introduced. The prototype system combines head-mounted, video-based gaze tracking with capacitive ...
  • Rantanen, Ville; Niemenlehto, Pekka-Henrik; Verho, Jarmo; Lekkala, Jukka (2010)
    A capacitive facial movement detection method designed for human-computer interaction is presented. Some point-and-click interfaces use facial electromyography for clicking. The presented method provides a contactless ...
  • Levanen, Toni; Talvitie, Jukka; Renfors, Markku (2012)
    The increase in the peak-to-average power ratio (PAPR) is a well known but not sufficiently addressed problem with data-dependent superimposed training (DDST) based approaches for channel estimation and synchronization in ...
  • Levanen, Toni; Renfors, Markku (2010)
    In this paper an iterative, interference cancelling receive structure for single carrier transmission using superimposed training is studied. We derive the analytical MSE limits for LMMSE channel estimator using perfect ...
  • Levanen, Toni; Renfors, Markku (2012)
    In this paper, we compare the energy efficiency of a single carrier multiple-input multiple-output communications in terms of the energy per data bit required to achieve desired performance level or throughput. The comparison ...
