视线追踪中一种新的由粗及精的瞳孔定位方法

基于图像处理的方法，采用了由粗及精的瞳孔定位思想，提出了一种高精度的瞳孔定位算法。该算法首先利用瞳孔区域的直方图，采用改进的最大类间方差法自适应地分割瞳孔区域，实现粗略定位，然后利用瞳孔灰度的梯度特性来精确定位瞳孔边缘点，最后在像素级瞳孔边缘点的基础上，采用亚像素定位方法，更精确地求得亚像素级瞳孔边缘点，并通过椭圆拟合的方法来精确确定瞳孔的中心位置。另外，针对瞳孔被遮挡的情况，本文提出了一种等距离补偿瞳孔的方法。多次实验结果证明了该算法对遮挡瞳孔的定位有较强的鲁棒性，可以准确地定位瞳孔的位置。      

Restricted mandibular opening complicating intraoral galeal flap reconstruction and radiotherapy: case report

The delto-pectoral flap has been used to repair burned scar in the faciocervical region for some years. However, its limited size restricts its application. Furthermore, direct transfer of the flap may result in a swelling and inexpressive face and the donor site needs skin grafting. To avoid the above disadvantages, we have tried pre-expansion of the flap. In this article, the authors report the experiences in the application of the method to eighteen cases, including the surgical procedure, the applied anatomy, and typical cases as well. Also included in the article are the comparison between various therapies to the burned scar of the face, the key points for successful pre-expansion of the delto-pectoral flap, accurately maintaining the desired position. The method has been proved to have many advantages and can be widely applied.

The accurate measurement,calculation, and control of steel hardenability

To control hardenability accurately it must be measured accurately. The Jominy test has been refined to do this. Extension of the test has also allowed accurate measurement down to 0.2 in. diam specimens. Illustrations of accuracy and reproducibility are given. Commercial steels show very wide hardenability bands and the influence of residual elements is profound. Correlation of accurately determined hardenability and composition has been examined using computer regression analyses. It is shown that the position of the Jominy curve can be calculated to within ±0.017 in. with 90 pct probability. The accuracy of the method is compared with previous systems. It is shown that other systems (e.g., Grossmann) are generally less accurate even over their best ranges of application. The use of hardenability control in induction hardening is discussed and the width of useful bands derived. Carbon content control is particularly important and it is shown how traditional methods result in inaccurate information. Hardenability control can produce economies to both steel producer and user. The use of control diagrams is discussed. This paper is based on a presentation made at a symposium on “Hardenability” held at the Cleveland Meeting of The Metallurgical Society of AIME, October 17, 1972, under the sponsorship of the IMD Heat Treatment Committee.     

Evaluation and Control of Iron and Steelmaking Slags through Electrochemical FeO Sensor

One of the greatest obstacles to the application of physical chemistry principles to the elucidation of slag‐metal reactions is a lack of knowledge of activities of the reacting species. To a large extent, oxygen potential of the slag phase governs iron and steelmaking practice. Without oxygen control by means of appropriate sensors, the behaviour of the other elements cannot be managed. In this paper, measurements of the FeO activity with various types of electrochemical FeO sensors will be described together with examples of their applications for improved strategies toward better practice for ladle metallurgy and sulphur and manganese distributions between slag and metal phases during steelmaking. Measurements of FeO activity have also been made in order to improve dephosphorization reactions. This type of work has led to significant reduction in volume of slag generated within the steelmaking vessel, which in turn, has important implications for refractory wear, metal yield, alloy recovery and improved productivity. Finally an on‐line sensor is described which permits the oxygen potential to be determined for both the metal phase and the slag phase during steelmaking in the BOF.
