title: Reviews of teacher education in New Zealand 1950–1998: Continuity, contexts and change

authors: Alcorn, Noeline

abstract: After a period of 40 years of relative political and professional consensus, teacher education in New Zealand since 1990 has undergone considerable change. This has taken place in a policy environment where the rhetoric of choice and accountability has been dominant and suspicion of professionals and academics widespread. This paper examines a series of major reports on teacher education in each decade since 1950, from the Consultative Committee chaired by Arnold Campbell in 1951 to the Green Paper of 1997, tracking both the professional expectations and the social contexts. It focuses in particular on the changing concepts of professionalism and accountability and argues that a new order needs to be built that incorporates wider perspectives but does not silence the professionals.

title: Towards optical flow in time-of-flight range imaging using the continuous wavelet transform

authors: Wise, JJ

abstract: Time-of-flight (ToF) range imaging cameras perform full-field distance measurement, but require multiple frames to be captured sequentially in order to construct a single range image. When motion occurs during data acquisition, artifacts appear that limit the accuracy of range estimates. Analysis of these artifacts finds that they take the form of spatial waves whose frequency encodes motion information. We therefore propose a new technique for measuring motion in Time-of-Flight range imaging based on the continuous wavelet transform (CWT). Synchrosqueezing is explored as a means of improving the accuracy of velocity estimates.
