block16.m

将一幅多媒体图像根据各个块的不同特性蔡用不同的编码方式

function block16(oiv16)
global bit_count point cell_count total_cell %total_val total_decode
ovic16=reshape(oiv16,1,256);
 for i=1:255
     if ovic16(i)~=ovic16(i+1)
       flag='1';
                  
      break
      end
         flag='0'; 
         end
        if flag=='0'
            bit_count=bit_count+9;
            point=cell_count;
            total_cell(point+1)=uint8(0);
            point=point+1;
            total_cell(point+1)=uint8(ovic16(1));
            cell_count=cell_count+2;
            return
         end    
        if flag=='1'
            for mm=1:2
               for nn=1:2
                 oiv88=oiv16((mm*8-7):(mm*8),(nn*8-7):(nn*8));
                 block8(oiv88);
               end
            end
        end
