of the flu virus. Vaccinations are a form of Adaptive Immunity classified as Artificially Induced Active Immunity. The vaccine presents a specific antigen into the body that triggers the primary immune response. T cells provide cellular immunity and B cells provide humoral immunity. Both work together to provide the immune response. First the weakened antigen fragment is inserted/injected into the body. A phagocyte will then engulf the abnormal antigen. Before destroying the bacterium a Class1 MHCP

the surface of DCs.(Kumar & Clark 2009 ) Once in contact, they migrate from the blood stream into the lymphatic system to further develop and begin replication.(3) T-Cells are differentiated during this process where the T-helper cell would activate B-cells whilst the other T-Cells develop into cytotoxic T-cells. This is the primary immune response. Until the same antigen is re-introduced again for the memory T-cell to proliferate do they initiate the secondary immune response. (5,6). DCs assist in

physics, cosmology, traffic (plate numbers), etc. We can also use this to recognize character for example to digitalize a book. We will talk about this last topic in this report: Optical Character Recognition (OCR). I. INTRODUCTION Once we have the b&w image we can start the segmentation process. To do that we can use the function “bwconncomp”. This function returns us a struct from where we can obtain the characters because it gives us all the connected components. Thus, we can use it to get all
