Within the field of statistics, a challenging problem is analysis in the face of missing information. Statisticians often have trouble deciding how to handle missing values in their datasets, as the missing information may be crucial to the research problem. If the values are missing completely at random, they could be disregarded; however, missing values are commonly associated with an underlying reason, which can require additional precautions to be taken with the model. In this thesis we attempt to explore the restoration of missing pixels in an image.

Another approach to handling missing values is to impute or estimate them. Missing value imputation has a long history in statistics and has been thoroughly researched. In essence, imputation uses information and relationships among the non-missing predictors to provide an estimate to fill in the missing value. Historically, statistical methods for missing data have been concerned with the impact on inferential models. In this situation, the characteristics and quality of the imputation strategy have focused on the test statistics that are produced by the model. The goal of these techniques is to ensure that the statistical distributions are tractable and of good enough quality to support subsequent hypothesis testing. The primary approach in this scenario is to use multiple imputations; several variations of the data set are created with different estimates of the missing values.
