Log视频由于进行了位宽压缩所以在普通显示设备上播放时对比度很低,色调是灰蒙蒙的,称为灰片,需要经过调色(grading)处理后才能变成正常的颜色。 Log is probably most suitable for shooting cinema, drama, music videos, and other types of footage where extensive post-processing, color correction, and “stylized...
The brightness of the image could vary a lot (so you can't rely "too much" on color detection). The can could be partly hidden on the sides or the middle and possibly partly hidden behind a bottle. There could be no can at all in the image, in which case you had to ...
Image Processing, Analysis and Machine Vision (附:这本书是图像处理与计算机视觉里面比较全的一本书了,几乎涵盖了图像视觉领域的各个方面。中文版的个人感觉也还可以,值得一看。) 数字图像处理 第三版 冈萨雷斯等著 Digital Image Processing (附:数字图像处理永远的经典,现在已经出到了第三版,相当给力。我的导...

这个方法和Jarrett [11]等人使用的局部对比度归一化有一些类似,但是我们的模型更符合"亮度归一化(brightness normalization)"这一范畴,因为我们没有减去均值。响应归一化使得我们模型的Top1错误率及Top5错误率分别降低了1.4%和1.2%。我们还用CIFAR-10数据集验证了响应归一化的效率:四层CNN没有归一化层时错误率为13%...
The basic rate of change of image brightness equation constrains the optical flow velocity.The velocity has to lie along a line perpendicular to the brightness gradient vector.The distance of this line from the origin equals divided by the magnitude of ().改变图像的亮度方程的基本税率约束光流速度...

Namely the equation is constituted of y=(1-d)y1+alphay2, where (y) is a synthesized brightness value for a certain output picture element,(y1) is a brightness value for a certain picture element in a normal image and)y2)is a brightness value for a picture element corresponding to a ...
Image Transformation Consider this equation G(x,y) = T{ f(x,y) } In this equation, F(x,y) = input image on which transformation function has to be applied. G(x,y) = the output image or processed image. T is the transformation function. ...
