An industrial material detection method and system based on feature extraction and contrast enhancement

PendingCN122510167Asuppress blurprevent dislocationImaging qualityImage detection
This invention discloses an industrial material inspection method and system based on feature extraction and contrast enhancement, belonging to the field of image inspection technology. It includes: S1, acquiring the transmitted signal using a digital flat panel detector and generating an original digital image based on the differences in X-ray absorption by different materials or defects; S2, performing uniformity correction and normalization enhancement on the original digital image, and achieving preliminary differentiation of different material regions; S3, dividing the original image data into processing domains based on the preliminary differentiation results, and performing differentiated enhancement processing based on the local feature attributes of each processing domain to generate a binary feature image. By integrating X-ray penetration imaging, multi-dimensional image enhancement, and a deep learning-driven intelligent rating system, this invention fundamentally solves the key technical bottlenecks in traditional industrial material inspection, such as inconsistent image quality, lack of material identification, and strong subjectivity in rating, achieving an automated, intelligent, and objective upgrade in industrial material defect detection.

The embodiment of the invention provides a bone microstructure parameter extraction method, computing equipment, a computer readable storage medium and a computer program product. The bone microstructure parameter extraction method comprises the following steps: firstly, carrying out super-resolution reconstruction on a CT (Computed Tomography) image to enhance the image quality; then, a first bone mask is generated through a global threshold value, a local adaptive threshold value is constructed in combination with local gray statistical characteristics, and a mask edge and a low-contrast region are subjected to reclassification to obtain a more accurate second bone mask; and then, noise connected domain elimination under volume constraint is performed on the second bone mask, and a fracture or a pseudo joint of the bone trabecula network is repaired based on morphological characteristics to obtain a high-fidelity bone tissue structure segmentation result. And finally, cortical bones are removed from the result to separate out cancellous bones, and bone microstructure parameters are extracted from the cancellous bones. According to the technical scheme provided by the embodiment of the invention, the accuracy of bone microstructure parameter extraction is improved.
