Abstract
The conventional computational integral-imaging reconstruction (CIIR) method has some drawbacks of intensity irregularity and brightness degradation in the reconstructed pane object images (POIs) due to its insufficient and uneven overlapping of the projected elemental images. Thus, in this paper, a modified CIIR (M-CIIR) technique is proposed to dramatically enhance the viewing quality of the computationally reconstructed object images. For this, a pixel-count matrix (PCM) is introduced in the CIIR process to calculate the number of overlapped pixels of the projected elemental images in the reconstructed object plane. Each pixel value of the reconstructed POI, then, is determined as the average of all overlapped pixel values. As the pixel values of the reconstructed POI are regulated by the PCM, viewing quality of the reconstructed POIs can be dramatically improved in the proposed method. In order to show the feasibility of the proposed method, experiments are performed, and the results are compared and discussed with those of the conventional method.
