查询词典 fir

By defining a discriminability function and utilizing some images with synthetic defects, a parameter selection method is proposed to adapt to various fabric types when the Gabor filter bank is applied in defect segmentation. It is argued that only the real part of Gabor filter works during segmentation; the radial orientation can be limited to horizontal and vertical direction; the radial frequency and the length of the FIR filter should depend on the basic frequency of the fabric texture.

本文通过定义分辨力函数，以合成疵点图像为研究对象，提出了在实时应用中对各种不同的纹理图像能快速确定Gabor滤波器组参数的方法：疵点分割中只需用到实Gabor滤波器；方位角只需取水平和垂直方向，径向中心频率和FIR滤波器长度的选取依赖于布面纹理的固有频率。

A Little Boy How I never could be tired with roaming about that huge mansion, with its vast empty rooms, with their worn-out hangings, fluttering tapestry, and carved oaken panels, with the gilding almost rubbed out---sometimes in the spacious old-fashioned gardens, which I had almost to myself, unless when now and then a solitary gardening man would cross me---and how the nectarines and peaches hung upon the walls, without my ever offering to pluck them, because they were forbidden fruit, unless now and then,---and because I had more pleasure in strolling about among the old melancholy-looking yew-trees, or the firs, and picking up the red berries, and the fir-apples, which were good for nothing but to look at ---or in lying about upon the fresh grass, with all the fine garden smells around me---or basking in the orangery, till I could almost fancy myself ripening too along with the oranges and the limes in that grateful warmth-or in watching the dace that darted to and Fro in the fish-pond, at the bottom of the garden, with here and there a great sulky pike hanging midway down the water in silent state, as if it mocked at their impertinent friskiness,---I had more pleasure in these busy-idle diversions than in all the sweet flavors of peaches, nectarines, oranges, and such like common baits of children.

In this paper, the FIR low-pass digital filtering method is first introduced for reducing the effects of noise signals in the experiment of velocity measurement of high-temperature flue gas flowing in pipe. The experimental results indicated that, only one peak presents in the cross-correlation graph, which is in good agreement with theoretical analysis result. Secondly, the temperature and pressure pulse signals of the high-temperature flue gas, obtained by thermocouple and pressure sensor, are introduced to explain the applicability of sensor characteristics.
