Özet:
In this thesis, Contemporary art and Bio art were examined in detail and information was given
about the artists and scientists working in this field. In addition, research has been carried out
on how abstract art is affected by science, and the emphasis of the effects on the works of the
artists has been tried to be made separately. It has been tried to convey the effects of the
reflections of bio art on painting art and abstract art on the way of transforming science into art.
In the first part of the thesis, necessary definitions were made about Abstract Art, and Wassily
Kandisky, the most important representative of abstract art, who made the most important
contribution to the taking of abstract art in the history of art, and his works were discussed. The
development of abstract art after 1940 and its transformation up to the present are discussed,
together with the changing world and the fact that art has changed.
In the second part of the thesis, the interaction between science, art and nature on
interdisciplinary interaction was emphasized, emphasizing that each of them feeds on each
other. Information was given about important artists in the history of art and their works, who
made the reflection of science, art and nature intertwined on works of art. In addition, researches
have been made in different art branches about its reflections on contemporary art.
In the third part of the thesis, there are studies of scientists and artists on the subject of turning
scientific studies into art, in which science is at the forefront. However, it has been emphasized
that there is a microorganism that is too small to be seen with the naked eye in science, and bioart is discussed as the field where it has become a work of art in terms of revealing this micro
world. Information was given about foreign, local, scientists and artists working in the field of
bio art and their works were given.

Abstract:
Multilevel image thresholding is an important image processing technique used to segment an image into
meaningful features at an advanced level. In this study, a web-based image processing tool has been developed for
multilevel image thresholding. This tool includes the newly proposed GWO-HS algorithm alongside nine different
optimization algorithms. Users can utilize any of these algorithms to obtain results for their desired image and
threshold levels. They can compare these results and export their outputs.
The proposed GWO-HS algorithm is a hybridization of Grey Wolf Optimization (GWO) and Harmony
Search (HS) algorithms. The performance of this algorithm has been compared with the performances of nine other
algorithms. Otsu, Kapur, and Tsallis entropy-based thresholding methods were used for the comparisons. In the
experiments, six well-known and widely used images in image processing were preferred. Thresholding was applied
to each image for levels ranging from 2 to 10. The results demonstrated that the proposed GWO-HS algorithm has
superior performance compared to other algorithms, especially for higher threshold levels.
