    • Provided are an apparatus and method for enhancing image quality of an input image captured by an image capturing device having an aperture with a plurality of openings employing different color filters. The image quality enhancing apparatus includes an ROI (region of interest) classifying unit classifying ROIs according to distances from the image capturing device of a captured input image by using a cluster-based image segmentation algorithm, a color channel registering unit determining motion vectors of color channels corresponding to the respective ROIs by analyzing a high frequency component of image data included in the ROIs, and moving the color channels based on the determined motion vectors to obtain a registered image of the respective ROIs, and an image fusing unit fusing the registered images of the respective ROIs to obtain a fused image.
    • 提供了一种用于增强由具有带有多个采用不同滤色器的开口的孔径的图像捕获装置拍摄的输入图像的图像质量的装置和方法。 图像质量提高装置包括ROI(感兴趣区域)分类单元,通过使用基于聚类的图像分割算法,根据捕获的输入图像的图像捕获装置的距离对ROI进行分类,颜色通道登记单元确定颜色的运动矢量 通过分析包括在ROI中的图像数据的高频分量,并且基于所确定的运动矢量来移动颜色通道以获得各ROI的登记图像,对应于相应ROI的通道,以及融合注册图像的图像定影单元 以获得融合图像。
