How To Install vspline-dev on Kali Linux

In this tutorial we learn how to install vspline-dev on Kali Linux. vspline-dev is header-only C++ template library for b-spline processing

Introduction

In this tutorial we learn how to install vspline-dev on Kali Linux.

What is vspline-dev

vspline-dev is:

vspline aims to be as fast as possible, yet mathematically precise. It’s main focus is interpolation of bulk data like sounds, images and volumes. vspline can handle

  • splines over real and integer data types and their aggregates:
  • all ‘*xel’ data, arbitrary number of channels (template argument)
  • single, double precision and long doubles supported (template argument)
  • several boundary conditions (mirror, reflect, periodic, natural)
  • spline degree up to 45 (runtime argument)
  • arbitrary dimensionality of the spline (template argument)
  • specialized code for 1D data
  • multithreaded code (pthread)
  • using the CPU’s vector units if possible (like SSE, AVX/2)
  • processes nD arrays with arbitrary shapes and strides

On the evaluation side it provides

  • evaluation of the spline at point locations in the defined range
  • evaluation of vectorized arguments with SIMD code
  • optional use of Vc for explicit SIMD code using intrinsics
  • evaluation of the spline’s derivatives
  • factory functions to create evaluation functors
  • specialized code for degrees 0 and 1 (nearest neighbour and n-linear)
  • mapping of arbitrary coordinates into the defined range
  • evaluation of nD arrays of coordinates (‘remap’ function)
  • discrete-coordinate-fed remap function (‘index_remap’)
  • generalized functor-based ‘apply’ and ’transform’ functions
  • restoration of the original data from the coefficients

To produce maximum performance, vspline has a fair amount of collateral code, and some of this code may be helpful beyond vspline:

  • multithreading with a thread pool
  • application of fundamental and SIMD functors to nD arrays
  • functional constructs using vspline::unary_functor
  • nD forward-backward n-pole recursive filtering
  • nD separable convolution
  • efficient access to the b-spline basis functions
  • precise precalculated constants (made with GNU GSL, BLAS and GNU GMP)
  • many examples, ample comments

vspline uses a three-step approach to splines: the first step is coefficient generation (including prefilering), the second step is generation of specific functors providing evaluation, the third is application of these functors to n-dimensional data. data handling is done with vigra data types, using vigra::MultiArrayView for handling strided nD arrays, and vigra::TinyVector for small aggregates. vigra::MultiArrayView is a thin wrapper combining an array’s address, dimension, data type, stride and shape, it’s easy to use it to ‘package’ raw data. vspline handles vector formation from interleaved data, peeling and re-interleaving automatically. vspline optionally uses Vc. Without Vc present, it triggers the compiler’s autovectorization by producing deliberately vector-friendly inner loops. vspline has been under development for several years and is extensively tested for scope coverage, reliability, precision and performance.

There are three methods to install vspline-dev on Kali Linux. We can use apt-get, apt and aptitude. In the following sections we will describe each method. You can choose one of them.

Install vspline-dev Using apt-get

Update apt database with apt-get using the following command.

sudo apt-get update

After updating apt database, We can install vspline-dev using apt-get by running the following command:

sudo apt-get -y install vspline-dev

Install vspline-dev Using apt

Update apt database with apt using the following command.

sudo apt update

After updating apt database, We can install vspline-dev using apt by running the following command:

sudo apt -y install vspline-dev

Install vspline-dev Using aptitude

If you want to follow this method, you might need to install aptitude on Kali Linux first since aptitude is usually not installed by default on Kali Linux. Update apt database with aptitude using the following command.

sudo aptitude update

After updating apt database, We can install vspline-dev using aptitude by running the following command:

sudo aptitude -y install vspline-dev

How To Uninstall vspline-dev on Kali Linux

To uninstall only the vspline-dev package we can use the following command:

sudo apt-get remove vspline-dev

Uninstall vspline-dev And Its Dependencies

To uninstall vspline-dev and its dependencies that are no longer needed by Kali Linux, we can use the command below:

sudo apt-get -y autoremove vspline-dev

Remove vspline-dev Configurations and Data

To remove vspline-dev configuration and data from Kali Linux we can use the following command:

sudo apt-get -y purge vspline-dev

Remove vspline-dev configuration, data, and all of its dependencies

We can use the following command to remove vspline-dev configurations, data and all of its dependencies, we can use the following command:

sudo apt-get -y autoremove --purge vspline-dev

Dependencies

vspline-dev have the following dependencies:
