Image mosaic (Mosaic) for a given image sequence is the first image sequence alignment positioning, and then fusion spliced to produce a seamless, high-resolution large-scale scene images. This paper discusses the calculation model in the wavelet transform in image processing and wavelet transform image stitching. This paper presents the optimal image mosaic method based on Wavelet transform and introduces a seamless optimization algorithm based on wavelet transform and its validity through a concrete example simulation.

Background: The development in the field of image reconstruction is growing rapidly along with the development of  CT Scan. In  the early stages of  MSCT abdominal artery is usually found  various kinds of vascular abnormalities such as stenosis, aneurism and others. Post processing image techniques commonly used include MPR and MIP. The purpose of this study is to determine whether there is a difference between MPR and MIP techniques and to know which one is better between the two.Methods: This  research was  quantitative study with experimental approach. The study was conducted at Bhakti Dharma Husada Surabaya Hospital  with 15 samples by performing reconstruction on vascular anatomical image of coronal examination of  abdominal MSCT. Assessment of anatomical information data is done by 2 respondents. Data analysis was done by kappa test followed by Wilcoxon sign rank test.Result : The results showed the difference between the post-processing of MIP and MPR on the coronal stages of the early arterial phase of the abdominal MSCT examination, based on the results of  non-parametric statistical test analysis (Wilcoxon) showed  a significant value of p value = 0.001. The result of MIP mean rank value (8,46) is higher than the mean rank value of MPR (1,50), it can be known that post proceeding MIP technique on coronal phase cuts early arterial examination of abdominal MSCT produces better anatomical image information.Conclusion: On examination of abdominal MSCT in the early arterial phase should be at the time of processing the image is also done by using post-processing MIP because more clearly than the MPR.
