histogram modification meaning in Chinese
直方图修正
Examples
- Histogram modifications and the forward and backward ( fab ) diffusion processes are combined for the image enhancement
在此基础上，通过对图像的梯度信息和直方图信息的合理组合，提出了基于全局信息的图像增强组合方法。 - The traditional image enhancement approaches include gray - scale transformation , histogram modification , histogram equalization , image smoothing and wiener filtration
传统的图像增强方法有灰度变换、直方图修正、直方图均衡、图像平滑和维纳滤波。 - The trade - off parameter between the fab diffusion and the histogram modification is controlled by the variance of the image noise and the image histogram
并利用图像直方图的根方差和图像噪声的根方差，构造了两种方法组合的权重因子，给出了权重因子的计算方法。 - For each gray image wavelet transform based on histogram modification is used to eliminate the disturbance of background . threshold , edge extraction , mathematics morphology methods are also used to process gray image
对于单幅灰度图，首先在直方图修正的基础上采用小波变换去噪技术，排除了背景图像噪声的干扰。 - It can accomplish the contrast reverse transformation , contrast linear enhancement , histogram modification , filter ( lowpass and highpass ) , and the writer give two new algorithms which has been realized in fpga , one is automatic gain linear enhancement , the other is complicated background restrain based on common knowledge
其核心部分采用altera公司的ep1k100qc208芯片，构造专用处理功能，实现了直方图统计与均衡化、高通滤波、 fir滤波、中值滤波等算法。同时提出了自动增益线性变换、基于知识的红外背景抑制二种新算法，并在fpga中实现。
