It is not a linear relation between the light output and the signals input of color CRTgraphics monitor,so the monitor property must be corrected(Gamma Correction beforetransforming signals input and its display colorimetry.This paper develops a mathematicmethod for the correction by a simple light meter,describes a visual checks which can be usedfor quick verification of the integrity of the correction,and finaly gives a example to build aHVC color solid for a color graphics monitor.

彩色CRT图形显示器的光输出与其信号输入之间并不呈线性关系,因此在完成信号输入与显示色度的线性变换之前必须对显示器进行线性校正(Gamma校正)。本文提出了一种用简单的测光仪完成这一校正的数学方法,和一种可用于快速检验校正结果的视觉检测方法,并给出在显示器上建立HVC色立体的应用实例。

Digital watermarking is a new method for copyright protection of multimedia in a networked environment. A new watermarking algorithm for still image based on classification of image features is presented in this paper. The strength of watermark is a constant in most of the current image watermarking schemes. In this paper, the strength of the watermark which is embedded in the block DCT coefficients of the image varies with the texture, edge and luminance feature of the image adaptively. Therefore, it can ensure...

Digital watermarking is a new method for copyright protection of multimedia in a networked environment. A new watermarking algorithm for still image based on classification of image features is presented in this paper. The strength of watermark is a constant in most of the current image watermarking schemes. In this paper, the strength of the watermark which is embedded in the block DCT coefficients of the image varies with the texture, edge and luminance feature of the image adaptively. Therefore, it can ensure the invisibility and enhance the strength of the watermark simultaneously. By exploiting the statistical properties of the watermark, the watermark can be detected reliably. Experimental results demonstrate that the watermark is robust to several processings such as JPEG compression, luminance altering, contrast altering, Gamma rectification, histogram balance, crop, etc.
