Engineering Contradiction Analysis
1Measurement precision
If traditional image interpolation methods are used to generate transition images between two input images, then the process is simple and fast, but the accuracy and information fidelity of the generated transition images deteriorate when the input images have significant differences in features such as textures and styles
Solution Approach 1:
The patent transforms the image interpolation problem from pixel-space operations to feature-space operations by extracting image features first. This dimensional transformation allows interpolation to occur in the feature domain where semantic information is preserved, rather than directly manipulating pixel values. The feature extraction and interpolation process maintains information fidelity while handling images with significant differences in textures and styles.
Solution Approach 2:
The patent introduces image features as an intermediary between the input images and the transition images. Instead of directly interpolating pixel values, the method extracts features from input images, performs interpolation on these features, and then reconstructs transition images from the interpolated features. This intermediary feature representation preserves important image information while enabling accurate interpolation even when input images have significant differences.
2Manufacturing precision
If feature extraction and high-dimensional latent space transformation are performed to improve interpolation accuracy, then the quality of transition images improves, but the computational complexity and processing time increase
Solution Approach 1:
The patent performs feature extraction and transformation to high-dimensional latent spaces as preliminary actions before the actual interpolation process. By pre-processing the input images to extract meaningful features and transform them into a suitable representation space, the method prepares the data in advance, making the subsequent interpolation more efficient and accurate. This preliminary feature extraction avoids the need for complex iterative optimization during the interpolation step itself.
3Reliability
If noise is added and decoding conditions are applied during the interpolation process, then the robustness and feature similarity of the generated transition images improve, but the computational steps and processing complexity increase
Solution Approach 1:
The patent applies noise addition and decoding conditions as preparatory measures to cushion against potential information loss during interpolation. By introducing controlled noise and establishing decoding conditions before the final image generation, the method ensures that important features are preserved and that the interpolation process is more robust to variations in input images. This prior cushioning prevents degradation of image quality while maintaining a relatively streamlined process.
