The purpose of this research is to develop an efficient model for human pose estimation (HPE). The main limitations of the study include the small size of the dataset and confounds in the classification of certain poses, suggesting the need for more data to improve the robustness of the model in uncontrolled environments. The methodology used combines MediaPipe for the detection of key points in images with a CNN1D model that processes preprocessed feature sequences. The Yoga Poses dataset was used for the training and validation of the model, and resampling techniques, such as bootstrapping, were applied to improve accuracy and avoid overfitting in the training. The results show that the proposed model achieves 96% overall accuracy in the classification of five yoga poses, with accuracy metrics above 90% for all classes. The implementation of the CNN1D model instead of traditional 2D or 3D architectures accomplishes the goal of maintaining a low computational cost and efficient preprocessing of the images, allowing for its use on mobile devices and real-time environments.
