Frequency spectrum image processing method and system

Abstract

The invention provides a frequency spectrum image processing method and system, and relates to the field of image processing. The method comprises the steps of determining magnification scale values of each pixel position in an X direction and a Y direction in a two-dimensional coordinate system based on an image size of an original frequency spectrum image and an image size of a magnified frequency spectrum image; for each pixel position of the original frequency spectrum image, based on the frequency spectrum density value at the current pixel position, calculating a color value of the frequency spectrum density value by using a color mapping formula, and taking the color value as a filling color value of the amplified frequency spectrum image at the amplification area at the current pixel position; and according to the color value of each pixel position of the original frequency spectrum image, performing color filling on an amplification area obtained after each pixel position is amplified according to the amplification scale value, thereby obtaining the amplified frequency spectrum image displayed in different colors. According to the scheme provided by the invention, the real-time spectrum display efficiency can be improved, and the requirement that transient signals are not lost by real-time spectrum analysis data is met.

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a spectral image processing method and system. Background technique [0002] Real-time spectrum analysis is used to continuously collect, analyze, and process communication signals containing transient characteristics, and statistic and synthesize a large amount of spectrum data into a spectrum density statistical image. There is a high requirement for the processing speed of spectrum display, and the spectrum image processing time must be less than the measurement statistics time, otherwise it will cause a serious problem of spectrum data loss. [0003] Ordinary software uses a nested loop to traverse the array matrix to map the original image data to a new array matrix, which has high time complexity and low efficiency, and cannot effectively meet the processing speed required for real-time spectral images.
