Abstract
With the background of infrared monitoring technology applied in forest fire in forest, as the image characteristics of low contrast and great noise, the method of using Fourier transform is proposed to strengthen the picture in frequency domain.The forest infrared thermal image is enhanced by the ideal low-pass filter, Butterworth high-pass filter and homomorphic filter, respectively. with. According to the comparison, homomorphic filter overcomes the defects of the low pass and high pass filter and enhances details and contrast of image. An enhanced index homomorphic filtering function has been explored. Both the theory analysis and the experimental results show that the method can improve the definition of image and make more satisfactory image.关键词
