Description: Wavelet-Based multimodal feature extraction is an advanced method that uses wavelet transforms to analyze and extract relevant information from data coming from multiple modalities, such as text, images, and audio. This approach relies on the ability of wavelet transforms to decompose signals into different scales and frequencies, allowing for the capture of both local and global features of the data. Unlike other feature extraction methods, wavelets provide a more flexible and adaptive representation, resulting in better identification of complex patterns in heterogeneous data. This method is particularly useful in applications where the integration of different types of data is crucial, such as in emotion recognition from facial expressions and voice tone. The versatility of wavelet transforms allows this approach to be applied in various fields, from computer vision to signal processing, facilitating the creation of more robust and accurate models in multimodal data analysis.
