There are many techniques available to approach reflectance-based shape recovery in appropriate fields of application [4]. For instance, three-source photometric stereo method may be used for generating height maps of a human face, a human hand, etc. As an example, the following figures show three input images generated by using Lambertian reflectance maps (Figure 1). Figure 2 shows the shape r...

The shape of the human erythrocyte is normally maintamed in vivo as a biconcave disc for 120 days. In vitro. the cell shape can be altered readily by amphipathic cornpounds; however. given time and an energy source. the cells can recover the discoid morphology. An active shape control mechanism is postulated to regulate erythrocyte shape. The shape recovery process is a necessary element in rev...

A novel shape memory polymer composite was fabricated by introducing various amounts of silicon carbide whiskers (SiCws) into a shape memory epoxy. The relationship between the thermomechanical properties of the system and structural changes were investigated via dynamic mechanical analysis, scanning electron microscopy, and bending tests. The results show that the bend strength of composites c...

Given that most current Structure From Motion (SFM) algorithms cannot recover true motion estimates, it is important to understand the impact such motion errors have on the shape reconstruction. In this paper, various robustness issues surrounding different types of quadratic shape estimates recovered from motion cue are addressed. We present a theoretical model to understand the impact that er...

In dentistry, pure gutta-percha (trans-1,4-polyisoprene (TPI)) is widely used as a main component of root canal filling materials. TPI has an interesting shape memory formed through cross-linking, and this characteristic is expected to be very effective for development of novel dental treatments; in particular, modification of the shape recovery temperature to the intraoral temperature (37 ̋C) ...

Given that most current Structure From Motion (SFM) algorithms cannot recover true motion estimates, it is important to understand the impact such motion errors have on the shape reconstruction. In this paper, we present a theoretical model to understand the impact that errors in the motion estimates have on shape recovery. Using this model, we focus on the recovery of second order shape under ...

Smart shape-memory polymers can memorize and recover their permanent shape in response to an external stimulus (for example, heat). They have been extensively exploited for a wide spectrum of applications ranging from biomedical devices to aerospace morphing structures. However, most of the existing shape-memory polymers are thermoresponsive and their performance is hindered by heat-demanding p...
