Vectorization-and-Edgereserved-Quantization-of-Ima
- 本文通过对JPEG图象压缩标准的分析,找到了一种解决这一问题的方法,即保边缘图象量化方法。在JPEG量化前,通过分析判断这一图象块是否为边缘所在块,对于边缘所在块采用较细的量化步长;对于其他块可使用较粗或者原始的量化步长进行量化,这样便可改善图象边缘处的质量。文中是利用了DCT 变换后的直流系数DC值来确定图象边缘块的,因为直流系数为这一图象块的平均亮度,如果相邻块的DC值变化较大,则它所包括的边缘细节就较多,否则说明这一图象块变化平缓,包含边缘少。根据DC值的变化我们可以大致决定这一块的量
AudioBar6
- 功能描述:这是一个示波器显示控件,能够完成类似于示波器的功能。最多可以同时显示8个通道的数据波形,在控件上鼠标单击右键切换波形全屏显示/正常显示,在控件上鼠标单击左键可以暂停/继续,波形颜色,悉数等可以设置参数调节。鼠标位于控件上时会有十字形的定位线(图中蓝色十字线),同时有半透明的窗口显示当前坐标。由于采用了向内存DC绘图然后贴到pic控件上的方法绘制波形,所以控件的大小可以在运行时任意改变。
