### Abstract

The authors consider efficient parallel solutions to basic image processing problems on parallel architectures with reduced number of processors. The first proposed organization has n**2 memory modules to perform several image processing computations on an n multiplied by n image. This SIMD (single-instruction-multiple-data-stream) architecture has simple overall organization, low processing requirements, and can be implemented using a limited VLSI chip set or off-the-shelf components. Many image computations which can be performed in O(n) time on a mesh-connected computer (MCC) with n**2 PEs (processing elements), can also be performed in O(n) time on this structure with n PEs. The authors also show that the proposed architecture with n processors has superior performance to other proposed architectures that are based on a linear array of n processors, even if each processor in the linear array has enough memory to hold an entire row or column of the image. A class of reduced hardware organizations with nk processors and n**2 memory modules, where 1 less than equivalent to k less than equivalent to n, is introduced. It can perform many computations related to single figures in O(n/k plus k) time and provides linear speedup in the range 1 less than equivalent to k less than equivalent to n**1**/**2.
