A hybrid deep learning approach was designed that combines with enhanced short-time Fourier transform (STFT) spectrograms and continuous wavelet (CWT) scalograms for pipeline leak detection. Such detection plays a crucial role in ensuring the safety integrity of fluid transportation systems. The proposed model leverages power STFT CWT to enhance capabilities. pipeline's acoustic emission signals during normal operating conditions undergo transformation using CWT, creating representing energy variations across time-frequency scales. To improve signal quality eliminate noise, Sobel denoising filters are applied scalograms. These filtered then fed into convolutional neural networks, extracting informative features harness distinct characteristics captured by both CWT. For computational efficiency discriminatory power, principal component analysis is employed reduce feature space dimensionality. Subsequently, leaks accurately detected classified categorizing reduced dimensional t-distributed stochastic neighbor embedding artificial networks. achieves high accuracy reliability detection, demonstrating its effectiveness capturing spectral temporal details.

Detecting pipeline leaks is an essential factor in maintaining the integrity of fluid transport systems. This paper introduces advanced deep learning framework that uses continuous wavelet transform (CWT) images for precise detection such leaks. Transforming acoustic signals from pipelines under various conditions into CWT scalograms, followed by signal processing non-local means and adaptive histogram equalization, results new enhanced leak-induced scalograms (ELIS) capture detailed energy fluctuations across time-frequency scales. The fundamental approach takes advantage a belief network (DBN) fine-tuned with genetic algorithm (GA) unified least squares support vector machine (LSSVM) to improve feature extraction classification accuracy. DBN-GA precisely extracts informative features, while LSSVM classifier distinguishes between leaky non-leak conditions.
