One-dimensional block matching motion estimation method and device

The invention relates to a one-dimensional block matching motion estimation method and device. The method comprises the following steps: collecting two continuous frames of images of a current frame and a previous frame as targets; extracting a matched macro block region of the current frame and a maximum possible occurrence region of a macro block at the same position of the previous frame; extracting a characteristic matrix in the row direction and a characteristic matrix in the column direction of the matched macro block region of the current frame by using the weight coefficient matrix, and the matching feature matrix of the row direction and the column direction of the maximum possible occurrence area of the macro block at the same position of the previous frame; using the feature matrix of the current frame and the matching feature matrix of the maximum possible occurrence area of the macro block at the same position of the previous frame to perform absolute error summation; andfinding the minimum absol
