ABSTRACT
Image resizing techniques are used to alter an image's proportions while retaining as
much of its visual information as feasible. The complexity analysis of different picture
resizing methods relies on the methodology employed. I'll go over the complexity
analysis for three popular picture scaling techniques in this section. These complexity
evaluations are basic recommendations, and they might change depending on how
certain algorithms are implemented and optimized. Additionally, a number of
variables, such as software optimizations, picture size, and hardware capabilities,
might affect an algorithm's real runtime speed. The study on the complexity of an
algorithm have great impact on the whole fields of computer science and digital image
processing. This study used Punia et al (2020) formula in calculating the space
complexity and simulation technique in clarity parameter analysis of Thumbnailator,
Marvin and Graphic 2Dimension algorithms to see which one among the algorithms
consumed less and more space after scaling in computer memory as well as clarity
maintenance in JAVA. Results from simulation analysis shows that Thumbnailator is
the best algorithm as it maintained the quality of the image and has the minimum size
compared to other algorithm, it also take half the size of the resize as other algorithm
or followed by graphics 2D second to Thumbnailator but Marvin is not far worse than
algorithm but it takes higher size but with good quality than graphics 2D.
