Provided is a depth image unfolding apparatus and method that may remove a depth fold from a depth image to restore a three-dimensional image. As an example of the methodology, a large number of antibody producing cells such as plasma cells are separated so that these individual antibody producing plasma cells are placed in individual wells. With these parameters, the dry density and gravimetric water content of the soil can be calculated using a predetermined relationship between apparent dielectric constant, bulk electrical conductivity, dry density and gravimetric water content. The pixel data synchronization module synchronizes the pixel data of the first and second images.
