Understanding how these statistics influence default parameter settings requires an understanding of data distribution. 2. **Statistical Assertions**: The assertion checks if `thresh_val` is greater than a specific percentile (95th). This requires knowledge about percentile calculations within non-uniform distributions. 3. **Integration with External Libraries**: The code integrates with `skimage.segmentation.slic` which adds complexity due to library-specific parameters like `n_segments`, `compactness`, `max_iter`, etc., requiring familiarity with SLIC algorithm nuances. ### Extension: 1. **Multi-modal Data Handling**: Extend functionality to handle multi-modal data where different channels might require different processing techniques. 2. **Adaptive Threshold Calculation**: Instead of using fixed percentiles (99th/95th), develop an adaptive method that determines thresholds based on more complex criteria such as histogram analysis or entropy measures. 3. **Parameter Optimization**: Implement an automatic parameter optimization routine that uses cross-validation or other techniques to determine optimal values for `num_clusters`, `thresh_val`, etc., rather than relying solely on heuristics. ## Exercise ### Full exercise here: **Objective**: Enhance the given function `[SNIPPET]` by implementing advanced features while maintaining its core functionality. ### Requirements: 1. **Multi-modal Data Handling**: - Modify `segment_kmeans` function such that it can handle multi-channel image stacks where each channel might require different processing. - Ensure that each channel’s segmentation respects its unique statistical properties. 2. **Adaptive Threshold Calculation**: - Replace static percentile-based threshold calculation with an adaptive method. - The new method should analyze histogram properties or use entropy measures for determining thresholds dynamically. 3. **Parameter Optimization**: - Implement an automatic parameter optimization routine within `segment_kmeans`. - Use cross-validation or another suitable method to determine optimal values for `num_clusters`, `thresh_val`, etc. ### Constraints: - Do not modify existing functionality unless necessary. - Ensure backward compatibility so that previous calls without additional parameters still work correctly. - Maintain performance efficiency. ## Solution python import numpy as np from skimage.segmentation import slic def adaptive_threshold(image_channel): hist, bin_edges = np.histogram(image_channel[image_channel > 0], bins=50) cdf = hist.cumsum() cdf_normalized = cdf / cdf.max() # Find threshold where CDF crosses certain percentage (e.g., above median) threshold_index = np.where(cdf_normalized >= cdf_normalized[len(cdf_normalized)//2])[0][0] return bin_edges[max(0, threshold_index -1)] def optimize_parameters(image_stack): # Placeholder function;
