机器人彩色视觉研究

本文介绍了一种适合于智能机器人的新的颜色识别方法以及根据该方法所研制的一套颜色识别系统,同时给出了初步的实验数据。该方法采用了先进的CCD图像传感器,并且利用了着色物体表面的色功率谱的积分来进行颜色识别。实验结果令人满意。     

Why the “stimulus-error” did not go away

Psychologists in the early years of the discipline were much concerned with the stimulus-error. Roughly, this is the problem encountered in introspective experiments when subjects are liable to frame their perceptual reports in terms of what they know of the stimulus, instead of just drawing on their perceptual experiences as they are supposedly felt. “Introspectionist” psychologist E. B. Titchener and his student E. G. Boring both argued in the early 20th century that the stimulus-error is a serious methodological pit-fall. While many of the theoretical suppositions motivating Titchener and Boring have been unfashionable since the rise of behaviourism, the stimulus-error brings our attention to one matter of perennial importance to psychophysics and the psychology of perception. This is the fact that subjects are liable to give different kinds of perceptual reports in response to the same stimulus. I discuss attempts to control for variable reports in recent experimental work on colour and lightness constancy, and the disputes that have arisen over which kinds of reports are legitimate. Some contemporary psychologists do warn us against a stimulus-error, even though they do not use this terminology. I argue that concern over the stimulus-error is diagnostic of psychologists' deep theoretical commitments, such as their conception of sensation, or their demarcation of perception from cognition. I conclude by discussing the relevance of this debate to current philosophy of perception.

浅探青花瓷釉

研究了历代青花瓷色调的变化 ,经研究发现 ,历代青花色调的变化与色料中着色元素钴、铁和锰的含量和比例密切相关 ;其次 ,色料中氧化铝的含量对历代青花色调也有影响 ,氧化铝含量低于 18%～2 0 %时 ,色料易流散 ,高于 18%～ 2 0 %时 ,花纹较清晰 ;青花瓷烧成温度应在 130 0～ 132 0℃ ,气氛为还原气氛 ;胎釉应与色料的烧成温度、气氛和升温速度相适应。     

历史街区城市色彩景观研究——以嘉兴月河历史街区为例

历史街区作为城市的重要场所,是商业和文化思潮的集散地,在其城市或所在地域起着明显的色彩地标的作用。历史街区的景观色彩受到所在地的地理环境、风土民情等诸多因素的影响。对历史街区景观色彩的研究不但是对古遗产的传承和保护,而且对地域性色彩文化的宣传推广也有着重要的作用。     

Calculation of impact factor of vibrator oscillation in offset printing based on fuzzy controller and genetic algorithm

In the inking system of an offset printing press,a vibrator roller distributes ink not only in the circumferential direction but also in the axial direction.In the control process,if ink amount is determined only by the dot area coverage without considering the impact of vibrator roller's oscillation,the printing colour quality will be reduced.This paper describes a method of calculating the impact factor of vibrator roller' s oscillation.First,the oscillation performance is analyzed and sample data of impact factor is got.Then,a fuzzy controller used for the calculation of the impact factor is designed,and genetic algorithm is used to optimize membership functions and obtain the fuzzy control rules automatically.This fuzzy controller can be used to calculate impact factors for any printing condition,and the impact factors can be used for ink amount control in printing process and it is important for higher printing colour quality and lowering ink and paper waste.
