Scene analysis system using a combined fuzzy logic‐based technique
Jyh‐Yeong Chang, Chien‐Wen Cho · Journal of the Chinese Institute of Engineers · 2002
This paper proposes a two‐stage scene analysis scheme using a combined fuzzy logic‐based technique. The first stage begins with generating fuzzy rules to describe the scene. Based on these fuzzy classification rules, each image pixel is inferred and then classified to the natural object category with the largest membership degree. The second stage involves a newly derived fuzzy K‐nearest neighbor algorithm that further refines the classification result obtained. With this second stage, the proposed system is robust because it is demonstrated to be insensitive to the variations of membership functions and image noise contamination. Simulations of real world images have shown that the proposed scheme is very successful and the results are visually confirmed by human observation. The satisfactory results achieved in this paper suggest the feasibility of developing similar systems for other types of images aiming at image description problems.
