AB  - Interpolation is a technique which is used to enhance or reduce 
  the size of digital images to correct spatial distortion. In convolution based 
  interpolation scheme, the quality of the scaled image depends upon the order 
  of convolution kernel. A better quality of interpolation can be achieved by 
  using higher order models but it requires complex computation and heavy memory 
  access time. Fast First Order Polynomial Convolution Interpolation Method is 
  one of the efficient methods for scaling images still there exists complexity 
  in generating weights. This study presents an area efficient Weighting Coefficient 
  Generation (WCG) circuit for digital image scaling. In the proposed hardware 
  architecture, the WCG circuit has decreased the hardware complexity substantially. 
  It includes only nine arithmetic components which is much less than the number 
  of components in the existing hardware architecture of WCG of Fast First Order 
  Polynomial Convolution Interpolation (FFOPCI) algorithm. The computational burden 
  is less when using the proposed architecture for generating the weighting coefficients 
  in FFOPCI algorithm. Thus, high quality scaled images can be obtained with low 
  computational burden when using the proposed architecture in FFOPCI algorithm.
