- Hough Transform: This technique is widely used for detecting straight lines in images. It can identify the location of lines even if they are broken or slightly distorted.
- Radon Transform: Similar to the Hough Transform, the Radon Transform can detect lines by integrating the image intensity over straight lines at various angles.
- Morphological Operations: Using morphological operations like dilation or erosion with a structuring element shaped like the lines you expect to find can help isolate or enhance those lines.
- Template Matching: If you know the shape and orientation of the cross lines, you can create a template of a cross line and use template matching to locate similar shapes in the image.
- Geometric Fitting: Algorithms like RANSAC (Random Sample Consensus) can be used to fit geometric primitives (like lines) to the data points, which is useful for detecting lines in the presence of noise or outliers.
- Edge Detection: Techniques like the Canny edge detector can be used to find edges in the image, which can then be analyzed to find lines.
- Machine Learning: If you have a labeled dataset, you can train a machine learning model to recognize the patterns of the cross lines.

The picture looks like cross lines.
I want to classify the points to find the cross line except for clustering.
Please suggest an alternative.

To classify points and find the cross lines in an image without using clustering, you can explore several image processing and computer vision techniques. Here are some alternative methods:
Each of these methods has its own strengths and may be more or less suitable depending on the specifics of the image and the lines you're trying to detect.
