成果介绍

本发明公开了一种图像处理方法及装置，应用于图像处理技术领域。该方法包括：将存在块效应的红外解压缩图像划分为呈矩形阵列分布的图像块。获取图像块的边界灰度信息，进而确定各图像块与相邻图像块的边界落差信息，进而得到图像块的落差信息。基于边界落差信息、落差信息以及预设的补偿信息构建图像的约束优化目标函数。根据约束优化目标函数确定目标补偿矩阵。目标补偿矩阵中的每个元素值为图像中位置与元素值在目标补偿矩阵中的位置相同的图像块的补偿信息的目标值，且均满足约束优化目标函数取得最小值的条件。根据目标补偿矩阵中的元素值，补偿图像的直流分量，并对补偿后的图像进行平滑处理。该方法可补偿图像中已损失的直流分量。
