Abstract:
Objective To study on wavelet transform in calcium sparks image de-noising when excitation contraction cou-pling(ECC) was studied and researched by scanning confocal microscopy,in order to elucidate the mechanism of ECC.But due to the noise exist in most calcium sparks image,it is hardly to recognize and analyze the useful information of calcium sparks.So how to increase the signal-to-noise rate is very important in calcium spark studying.Methods By using the self-developed software based on multi-scale wavelet transform to remove the noise exists in the calcium sparks images.Results The experiments shows that the method can be increased the signal-to-noise rate in about 80 calcium sparks images.Con-clusion The new method for calcium spark expression and spatial and temporal analysis is provided.
