Residual Attention Image Captioning for Gaming Scenes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image captioning in gaming environments is challenging due to the lack of available datasets and the difficulty in generating human-understandable natural language descriptions from images, particularly in capturing key visual aspects of unstructured objects and scenes.
Innovation Solution
A system utilizing a convolutional neural network (CNN) processes images to generate feature maps, attention vectors, and pooled feature vectors, which are then combined to input into a caption generation network, employing residual top-down attention mechanisms to improve feature representation and caption generation, especially in gaming scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional image captioning methods are used, then general image descriptions can be generated, but gaming image captioning accuracy deteriorates due to lack of domain-specific datasets
Solution Approach 1:
The patent transforms gaming images into synthetic training datasets by modifying image parameters and generating corresponding captions. This creates domain-specific training data that improves captioning accuracy for gaming images without requiring actual gaming image datasets, resolving the contradiction between needing domain-specific adaptation and lacking available data.
Solution Approach 2:
The system creates synthetic copies of gaming images with annotated captions by processing generic images through game engine simulations. These copied and transformed images serve as training data that enables the model to adapt to gaming-specific visual characteristics, improving both accuracy and domain adaptability.
2Measurement precision
If detailed feature extraction is performed to capture key visual aspects, then caption quality improves, but computational complexity increases
Solution Approach 1:
The patent divides the image processing into segmented stages: initial feature extraction, attention-based key feature selection, and hierarchical caption generation. This segmentation allows detailed visual aspect capture while managing computational complexity by processing only relevant features at each stage rather than all possible features simultaneously.
Solution Approach 2:
The system extracts and isolates only the key visual aspects relevant to gaming scenes using attention mechanisms, rather than processing all image features. This extraction of essential features maintains caption quality while reducing the computational burden of processing unnecessary detailed information.
3Loss of information
If attention mechanisms are used to focus on key features, then information retention improves, but processing time increases
Solution Approach 1:
The patent applies attention mechanisms during the training phase to pre-identify and weigh key features, storing these attention weights for reuse during inference. This preliminary action during training reduces processing time during actual caption generation while maintaining information retention, as the system doesn't need to recalculate attention weights for every new image.

AI summary
For image captioning such as for computer game images or other images, bottom-up attention is combined with top-down attention to provide a multi-level residual attention-based image captioning model. A residual attention mechanism is first applied in the Faster R-CNN network to learn better feature representations for each region by taking spatial information into consideration. In the image captioning network, taking the extracted regional features as input, a second residual attention network is implemented to fuse the regional features attentionally for subsequent caption generation.
