Edge detection gives poor results when the input image contains noise, blur, or weak contrast. In the developed prototype, the same edge detector did not behave in the same way for all uploaded images. Some noisy images produced many false edge pixels, while blurred images lost useful object boundaries. To handle this problem, this paper describes a Flask-based system in which image restoration is carried out before edge detection. The uploaded image is first examined through variance, standard deviation, impulse-noise ratio, and Laplacian variance. These values guide the restoration choice through learned bucket mapping, fuzzy rules, or a simple fallback decision. The restoration stage uses Gaussian, median, non-local means, bilateral filtering, and an optional DeblurGAN-v2 path. After restoration, Canny, Sobel, Prewitt, or adaptive thresholding is applied to obtain the edge output. The web interface shows the original image, restored image, edge map, and evaluation values. The experiments suggest that choosing the filter from the image condition is more practical than applying one fixed preprocessing method to every image.
KEYWORDS
This paper described a condition-aware image restoration and edge detection system built using Flask. The image is examined before edge extraction using variance, standard deviation, impulse-noise ratio, and Laplacian variance. Based on these values, the system selects a restoration method using learned buckets, fuzzy rules, or fallback logic. Testing shows that different degradations need different preprocessing choices. Median filtering helps in impulse-noise cases, bilat-eral filtering preserves strong boundaries during smoothing, and non-local means improves random-noise cases at the cost of extra processing time. The current metric values can be improved further, but the system provides a practical starting point for restoration-assisted edge extraction in a web appli-cation.
