Reconstruction of Signal using Interpolation

Signal processing techniques are essential for accurately converting continuous signals to digital formats and vice versa. When a continuous signal is sampled with a period T, the resulting sampled signal exhibits replicas of the original spectrum in the frequency domain, spaced at intervals equal to the sampling frequency. To handle this sampled signal, a zero-order hold method can be applied, which creates a piecewise constant signal by retaining each sample's value until the next sampling...

This study introduces an adaptive LBG VQ algorithm for improved lossless compression of multi-spectral LASIS images. The novel algorithm significantly enhances compression ratios compared to conventional methods.

Area of Science:

  • Digital Image Processing
  • Data Compression
  • Machine Learning

Context:

  • The LBG VQ algorithm, developed in 2009, is a vector quantization method.
  • Existing LBG VQ algorithms face challenges with error quantification and increased bit usage for larger indices.
  • Interferential multi-spectral images present unique lossless compression challenges.

Purpose:

  • To propose an adaptive LBG VQ algorithm based on a point-to-line model.
  • To enhance the lossless compression performance of interferential multi-spectral images.
  • To reduce error quantification and avoid increased bit usage in vector quantization.

Summary:

  • An adaptive LBG VQ algorithm is presented, extending the 2009 LBG VQ algorithm using a point-to-line model.
  • This new algorithm achieves reduced error quantification and avoids increased bit rates associated with larger indices.
