本书全面介绍了机器视觉，提供了所有必须的理论工具，说明了这些理论工具怎样在实际的图像处理与机器视觉系统中的应用，特点是包括了许多计算机练习（这些练习对透彻理解实用图像处理算法很有帮助）。作者从对数学原理的复习开始，然后讨论了图像处理中的关键问题，例如图像的描述与表征、边缘检测、特征抽取、分段、纹理与形状等。本书注重应用，两个再现的主题是一致性（这是解决机器视觉问题主要的基本原理结构）和优化（用于实现这些方法的数学工具）。

We.conside. the.proble. of inducing withdrawal re.le. on a te.t subje.t via e.posure.to a millime.e. wave.be.m. In our physical mode., the.e.are.10 physical parame.e.s affe.ting the.occurre.ce.of withdrawal re.le.. Our goal is to pinpoint the.role. of the.e.physical parame.e.s in inducing withdrawal re.le.. We.first carry out non-dime.sionalization to re.uce.the.mode. to a non-dime.sional syste. of only 3 composite.parame.e.s: non-dime.sional be.m powe. de.sity, non-dime.sional be.m radius, and non-dime.sional e.posure.time. If the.be.m powe. is ke.t on and ste.dy, withdrawal re.le. occurs e.e.tually;the.shorte.t e.posure.time.for inducing withdrawal re.le. corre.ponds to the.smalle.t e.e.gy consumption at the.give. powe. de.sity and be.m radius. In the.2D space.of powe. de.sity and be.m radius, the.ove.all minimum e.e.gy occurs at the.corne. of ve.y large.powe. de.sity and ve.y small be.m radius, which also produce. a ve.y large.value.of maximum skin te.pe.ature.and a long time.to withdrawal re.le.. To re.uce.the.burn injury risk, we.introduce.a cap on the.maximum skin te.pe.ature. At e.ch give. total be.m powe., we.carry out optimizations with re.pe.t to the.be.m radius, constraine. by the.pre.cribe. te.pe.ature.cap. The.e.e.gy consumption varie. ne.ative.y with the.pre.cribe. te.pe.ature.cap: a lowe. te.pe.ature.cap can be.accommodate. only with a highe. e.e.gy consumption via the.ve.ue.of a large. be.m radius. The.e.e.gy consumption is re.ative.y flat with re.pe.t to the.total be.m powe. and attains a minimum at a mode.ate.y large.total be.m powe.. The.time.to withdrawal re.le. is approximate.y inve.se.y proportional to the.total be.m powe.. Our analysis de.onstrate. that a mode.ate.y large.total be.m powe. is a good compromise.to achie.e.both low e.e.gy consumption and short time.to withdrawal re.le..

We.conside. the.psychophysical e.pe.ime.ts in which the.te.t subje.t’s binary re.ction is de.e.mine. by the.pre.cribe. e.posure.duration to a stimulus and a random variable.subje.tive.thre.hold. For e.ample. whe. a subje.t is e.pose. to a millime.e. wave.be.m for a pre.cribe. duration, the.occurre.ce.of flight action is binary (ye. or no). In e.pe.ime.ts, in addition to the.binary outcome. the.actuation time.of flight action is also re.orde. if it occurs;the.de.ay from the.initiation time.to the.actuation time.of flight action is the.human re.ction time. which is not me.surable. In this study, we.mode. the.random subje.tive.thre.hold as a We.bull distribution and formulate.an infe.e.ce.me.hod for e.timating the.human re.ction time. from data of pre.cribe. e.posure.durations, binary outcome. and actuation time. of flight action colle.te. in a se.ue.ce.of te.ts.
