Image enhancement and edge detection algorithms for improving visual quality and identifying object boundaries
Applying homomorphic filtering to images followed by local histogram equalization can achieve blur enhancement effects, suitable for applications such as thin cloud removal in remote sensing images. However, this approach requires further refinement and research for optimal results.
Wavelet Transform-Based Image Enhancement with Complete Implementation Workflow
Image enhancement technology based on fractional-order differentiation, where the code leverages gradient information to better enhance high-frequency components while nonlinearly preserving low-frequency regions. Implementation typically involves constructing fractional differential masks and applying convolution operations to extract multi-scale features.
2. Image Enhancement: Image enhancement, also known as image sharpening, aims to strengthen detail information such as contour edges in images. Similar to image smoothing, image enhancement can be performed in both spatial and frequency domains. For spatial domain sharpening: subtracting the original image from a processed version yields the sharpened image g(i,j), i.e., g(i,j) = f(i,j) - α[f(i+1,j) + f(i-1,j) + f(i,j+1) + f(i,j-1) - 4f(i,j)] = f(i,j) + 4α[f(i,j) - avg]. Here α is an adjustable factor controlling sharpening intensity, where 1/4 represents the average gray value of the 4 neighboring points around the sharpened pixel.
