    Abstract

    Image quality measures to analyze the quality of color and infra-red images acquired at various time instants of the day (morning, noon, evening) are discussed in detail with sufficient statistical results. Images are captured once every 30 minutes all through one day and night. It is observed that color images are efficient only under good lighting conditions with responses to metrics being abrupt during dawn and dusk, whereas IR images are influenced to a certain extent by illumination and contain sufficient information even under less favorable conditions. IR responses to metrics are consistent throughout day and night as expected. It is presumed that this analysis would be helpful in deriving a weighting factor that can be used in the fusion of EO and IR images.
