【摘要】 TV图象输入是把摄象镜头取得的代表图片、实际景物中各点亮度的二维信息以数字形式存于计算机中。本文提出一种用硬、软件结合实现(静止)TV图象输入的方法,并介绍按照这一方法研制成功的输入装置。 输入A/D转换由软件控制在计算机中进行,因而使硬件设计简化,同时降低了设备成本。该装置可直接获取指定阈值下的二值图,并能对图象中任意抽取的二值影象进行显示、组合、装配而得到低于最大灰阶的任意灰度级图象。在某些特定的应用(如景物分析、图案处理等)场合,具有对图象进行分割处理的能力。更多还原

【Abstract】 A TV image input is to convert two-dimensional information, which represents the brightness at each point of a photograph or a natural image acquired by a telecamera, into a numerical form and to store it in a computer. A method of combining hardware with software to get static TV images is proposed and an input device developed.Input A/D conversion is carried out by software control, thus it simplifies the hardware design and reduces the cost. Such a device can acquire a two-valued image at a specified threshold suitable for display, can combine and/or assemble two-valued images, that are arbitrarily abstracted from an image, to obtain an arbitrary gray level image under the maximum gray scale. In some special applications (such as scene analysis or design processing etc.), this device is capable of segmenting images.更多还原
