As bean beetle embryos develop, time lapse photographs of their eggs exhibit varying levels of brightness that correspond to different stages of maturation. This signal can be analyzed to pinpoint the timing of these various stages. We have developed an averaging method based on a modified Haar wavelet technique to identify these changes visually. This method has been studied for both accuracy and precision through a process of randomized simulations at different levels of signal noise. The results of this study have supported the efficacy of this method, demonstrating its usefulness in analyzing a wide variety of signals.
