The invention discloses a quick defogging processing assembly for fog images. The quick defogging processing assembly for the fog images comprises a video input checking module, a video input statistic module, a video processing module, a video output module and an external storage controlling module, wherein the video processing module is the core of the quick defogging processing assembly and comprises a first-frame removing unit, a frame frequency controlling unit, a pixel minimum extracting unit, a local minimum extracting unit, an image edge expanding unit, a row filtering unit, parallel column filtering units and an enhancement processing unit. By utilizing a quick Gaussian convolution algorithm, the quick defogging processing assembly for the fog images is simple in structure and algorithm, low in realization difficulty and capable of greatly saving sources and reducing delays; by utilizing the multiple parallel column filtering units for row and column filtering of video streaming, the quick defogging processing assembly for the fog images reads data by rows during processing and then skips by columns, and can acquire multiple columns of data simultaneously and input the same into multiple Gaussian row filtering circuits for parallel processing synchronously, so that lost time for skipping by column addresses is compensated, and instantaneity for defogging processing is guaranteed.
