The Use of entropy for visual diversity assessment on residential streetscapes

Abstract

This study was conducted with the objective of finding out the applicability of entropy values for the assessment of visual diversity on residential streetscapes. The visual diversity on streetscapes occurs when the visual elements on streetscapes show a kind of difference to each other. Measuring of these differences among visual elements could be carried out using different methods. In this research, the entropy calculations were used of differences among visual elements to explain visual diversity numerically. For this data were collected from 30 residential streetscapes representing low to high housing densities. The sequential perspective views of streetscapes were analyzed for 6 visual attributes named, shape of houses, shape of roofs shape of windows,height color and the appearance of boundary walls of premises and for each attribute the entropy value was separate calculated. .ed According to the calculations, the residential street capes show high diversity variations. largely due to shape of the rooms and the appearance of boundary walls of premises. subsequently the sum of the each attribute the entropy values was considered as the total entropy for each streetscape. A field survey was the correlation building used to find out “Se 'SrovVL the, entropy could be success®, applted mease the visual diversity numerically on residential streetscapes.

“Se 'SrovVL the, entropy could be success®, applted mease™ the visual diversity numerically on residential streetscapes.
