This report discusses a study on image measurement based on fractal dimention for quantization or evaluation. Recently we have reported a method of the fractal-based quantization for evaluation a state of coagulation on activated sludge in a disposal plant. In order to calculate fractal dimension, we adopted the box-counting method, which is very fit and easy on image processing. In this method, however, the fractal dimension is calculated by counting pixcels which show target objects such as flocs in the sewage. Therefore it sometimes is considered that the value of the dimension is similar to a rate occupied these pixels. We have studied a comparision between the fractal dimension and the occupied rate by experiments on three samples of activated sludge, coagulant, PAC (Poly-Aluminum Chloride). In this paper we show both of the experimental results and describe the effect of the fractal dimension by the box-counting.
