Hi 수민 안,

I understand that you are interested in predicting future frames in a video sequence based on the analysis of previous frames using MALTAB.

Yes, it is possible to predict future frames of a video based on previous frames using MATLAB. The paper referenced, " EIDETIC 3D LSTM: A MODEL FOR VIDEO PREDICTION AND BEYOND," discusses a deep learning approach to video frame prediction. MATLAB has robust support for deep learning through its “Deep Learning Toolbox,” which can be used to implement and train predictive models like the one described in the paper.

Here is an overview to approach this task in MATLAB:

• Gather and Preprocess Data: Collect a dataset of videos to train the predictive model. Preprocess the frames by resizing, normalizing, and converting them into a sequence of images or a four-dimensional array (for batch processing).
• Define the Model: Define a predictive coding network or another suitable deep learning architecture using MATLAB's Deep Learning Toolbox. Use layers like convolutional LSTM (Long Short-Term Memory) layers, which are often used for sequence prediction tasks involving video.
• Train the Model: Use the “trainNetwork” function to train the model on the pre-processed video data. One needs to specify the training options, including the learning rate, number of epochs, and any regularization techniques.
• Evaluate the Model: After training, evaluate model's performance on a test set to see how well it predicts future frames. Use metrics relevant to the application, such as Mean Squared Error (MSE) for pixel-wise accuracy.
• Predict Future Frames: Once the model is trained and evaluated, use it to predict future frames of a video. Do this by feeding a sequence of frames into the model and generating the next frame(s).
• Postprocess Predictions: Depending on the application, one might need to postprocess the predicted frames, such as rescaling them to their original size or applying filters to enhance their quality.

The MATLAB documentation provides extensive resources on using the Deep Learning Toolbox, including examples of working with video data and LSTM networks. While the exact architecture and training process might differ from the one described in the paper, MATLAB's flexibility allows to implement custom layers and loss functions if needed.
