A level set based detail extraction method from images is presented in this paper. The method uses level set to encode the large-scale variation in the image and extracts detail from this variation. This method can compute the detail from images quite fast. The separated detail can be used for compensating the detail loss in High Dynamic Range (HDR) image compression using global tone mapping a...

New shock wave data for Bamle enstatite (Mgo. s•,Feo.•JSiOs in the range from 60480 kb indicate a Hugoniot elastic limit of 67 ñ 10 kb and a possible phase-transition-produced shock front of 135 _ 10 kb amplitude. Above the latter shock pressure, states in a mixedphase regime are achieved up to •350 kb, above which the Hugoniot states are believed to represent the equation of state of a shock-i...

The effects of carbon content on the dynamic and static softening mechanisms of Ti microalloy steels were investigated both in ferrite and austenite regions. &#10The results obtained showed that recrystallization rate decreased as the percentage of carbon content was increased from 0.0035 to 0.110. This is due to the Ti(CN) and TiC precipitates and also the free carbon content. In the ferrite r...

We analyze wire-tape channels with secure feedback from the legitimate receiver.We present a lower bound on the transmission capacity (Theorem 1), which we conjecture to be tight and which is proved to be tight (Corollary 1) for Wyner’s original (degraded) wire-tape channel and also for the reversely degraded wire-tape channel for which the legitimate receiver gets a degraded version from the e...
