Performance Improvement of Automatic Facial Midline Detection by Chain–coded Merlin–Farber Hough Transform
application/pdfWe propose a novel approach for detection of
the facial midline from a frontal face image. The facial mid-
line has several applications, for instance reducing computa-
tional cost required for facial feature extraction (FFE) and post-
operative assessment for cosmetic or dental surgery. The pro-
posed method detects the facial midline of a frontal face from an
edge image as the symmetry axis using the Merlin–Faber Hough
transformation. Experimental results on the FERET database
indicate that the proposed algorithm can accurately detect mid-
lines of face images with different scales and rotation.departmental bulletin pape

周波数応答問題における領域最適化解析 (力法によるアプローチ)
This paper describes a practical method of numerical analyses for domain optimization problems of linear elastic continua excited with a constant frequency. In this paper we deal with the minimization of the strain energy, the kinetic energy and the absolute value of mean compliance. We apply the traction method that was proposed as a solution to the domain optimization problems in elliptic boundary value problems. In this paper we formulate the domain optimization problems using the speed method and drive the shape gradient functions by the Lagrange multiplier method. The validity of basing this approach on the traction method using the derived shape gradient functions is confirmed through the results of numerical analyses of the beamlike plate problems.journal articl
Possible molecular mechanism of cold stress in rice.
<p>Under cold stress <i>Osa-miR319b</i> is down-regulated, leading to the repression of its targets and possibly the up-regulation of ROS (arrow with dashed line), which in turn inhibits cold tolerance. Under cold stress <i>DREB1/CBF</i> is up-regulated, and <i>Zat12</i> down-regulated CBF transcript expression, and account of ROS up-regulated <i>Zat12</i> transcript expression which in turn increases cold tolerance. However, it is possible that <i>Osa-miR319b</i> induces the expression of <i>DREB1/CBF</i> (arrow with dashed line and question mark).</p
Molecular confirmation of <i>OsPCF6</i> and <i>OsTCP21</i> transgenic rice.
<p>(A) <i>OsPCF6</i> and <i>OsTCP21</i> expression in wild-type and transgenic rice. Total RNAs from 2-week-old wild-type and transgenic rice plants were isolated, reverse-transcribed, and analysed by real-time reverse-transcription PCR. cDNAs were normalized using the <i>Ef1-α</i> gene. Data are the means ± SE of three biological replicates. Asterisks indicate statistically significant differences (**P<0.01) between WT and transgenic lines (OE and Ri). (B) Southern blot analysis of <i>OsPCF6</i>. (C) Southern blot analysis of <i>OsTCP21</i>. The WT rice genomic DNA was used as negative control.</p
Effect of cold stress on <i>OsPCF6</i> and <i>OsTCP21</i> in wild-type and transgenic plants.
<p>Left: wild-type, <i>OsPCF6</i> and <i>OsTCP21</i> transgenic plants (OE and Ri) without stress treatment; right: wild-type and transgenic seedlings treated with 4°C for 7 d followed by 10 d of recovery.</p
Expression levels of some cold-responsive genes in wild-type plants and <i>OsPCF6</i> and <i>OsTCP21</i> transgenic plants.
<p>(A) Expression levels of <i>DREB1A</i> and <i>DREB2A</i> gene in transgenic lines and wild-type plants. (B) Expression levels of ROS scavenging genes (<i>Os01g22249</i> and <i>OsSIK1</i>) in transgenic lines and wild-type plants. (C) Expression levels of putative proline synthase gene (<i>J033099M14</i>) in transgenic lines and wild-type plants. Data are the mean ± SE of three biological replicates. Asterisks indicate statistically significant differences (*P<0.05) between WT and transgenic lines.</p
<i>Osa-miR319b</i> overexpressing plants showed delayed development and widen leaf.
<p>(A) Gross morphology at 0 to 7-day-old seedlings phase of WT and transgenic plants; (B) Transgenic plants showed 14 d delaying of heading time comparing with WT. (C) The <i>Osa-miR319b</i>-overexpressing transgenic plants exhibited wider leaves than WT controls.</p
