[其他] 基追踪

关于基追踪(BP),在压缩感知重构中我们所待求解的问题是L0范数问题,因为L1范数与L0范数等价,所以将L0范数转换为L1范数问题来求解,基追踪是将L1范数问题转为成为线性规划问题来进行求解,博主还提到了基追踪降噪问题,是转换为二次规划问题来进行求解的,但是这类凸优化问题计算复杂度高,重构时间长
As for base pursuit (BP), the problem we need to solve in the reconstruction of compressed sensing is l0 norm problem. Because L1 norm is equivalent to l0 norm, l0 norm is converted to L1 norm problem to solve. Base pursuit turns L1 norm problem into linear programming problem to solve. Blogger also mentioned that base pursuit noise reduction problem is converted to quadratic programming problem to solve But this kind of convex optimization problem has high computational complexity and long reconstruction time (2021-04-10, matlab, 2KB, 下载2次)

这是一个M/M/C/∞排队系统,其中顾客按照泊松流输入,服务时间按照负指数分布,有C个服务台的单列多台并列服务系统。在这种系统,顾客到达系统后排成一个队列,然后到空闲的服务台接受服务,而每个服务台的服务时间都服从相同参数的负指数分布,服务完毕后顾客自动离去。
This is a M/M/C/ infinity queueing system, where the customers enter the Poisson flow, the service time is distributed according to the negative exponent, and there are C single row multiple parallel service systems of the service stations. In such a system, customers arrive at the system in the rear row into a queue, then receive service at the idle service desk, while the service time of each service station obeys the negative exponential distribution of the same parameter. After the service is finished, the customer automatically goes away. (2018-03-24, matlab, 11KB, 下载7次)

[图形图像处理] ransac

隨機抽樣一致算法(RANdom SAmple Consensus,RANSAC)。它採用疊代的方式從一組包含離群的被觀測數據中估算出數學模型的參數。 RANSAC是一個非確定性算法,在某種意義上說,它會產生一個在一定機率下合理的結果,而更多次的疊代會使這一機率增加。
Ransac algorithm (RANdom SAmple Consensus, RANSAC). It uses an iterative way to estimate the parameters of the mathematical model a set of observed data contains outliers in. RANSAC is a non-deterministic algorithm, in the sense that it will produce a reasonable result in a certain probability, and iterative more times will increase the chances.

[图形图像处理] Floyd_Steinberg_Dithering

有序抖动也是一种常用的半色调技术方法,可以说是最简单的领域处理过程的方 法。它是用一个固定大小的阈值矩阵在原始灰度图像上面一边“移动”,一边比较。如 果原始图像中像素的灰度值大于相应阈值矩阵中的阈值,那么抖动后该像素的值为1 (白 色),否则为0(黑色)。
Ordered dithering is also a common halftoning method, is the simplest way to process the fields. It is a fixed size in the threshold matrix at the side of the raw grayscale image " move" , while comparison. If the gray scale value of the pixel in the original image is larger than the threshold value matrix corresponding to a threshold value, then the dithering of the pixel value of 1 (white), otherwise as 0 (black).
