Part 1: Image Processing and AnalysisInternational audienceProduct Recognition is a challenging problem in many practical applications. This paper presents a new approach for product recognition. By utilizing a set of crawlers our task is to extract informative content from web pages and automatically recognize products found on web pages. A set of images is extracted from each web page and then a new “content-based” image retrieval technique is performed to rank the images from our product catalog. The proposed content-based image retrieval technique utilizes the Empirical Mode Decomposition and processes the first extracted component of the source image. This component maintains the highest local spatial variations of the source image. An adaptive local-threshold technique is applied for the extraction of edges. A quantized and normalized histogram is created for the representation of images. Simulation results reveal that the proposed method is a promising tool for the challenge task of product recognition

Recently, research endeavors have shown the potentiality of Cycle-Consistent Adversarial Networks (CycleGAN) in style transfer. In Cycle-Consistent Adversarial Networks, the consistency loss is introduced to measure the difference between the original images and the reconstructed in both directions, forward and backward. In this work, the combination of Cycle-Consistent Adversarial Networks with Fast and Adaptive Bidimensional Empirical Mode Decomposition (FABEMD) is proposed to perform style transfer on images. In the proposed approach the cycleconsistency loss is modified to include the differences between the extracted Intrinsic Mode Functions (BIMFs) images. Instead of an estimation of pixel-to-pixel difference between the produced and input images, the FABEMD is applied and the extracted BIMFs are involved in the computation of the total cycle loss. This method enriches the computation of the total loss in a content-tocontent and style-to-style comparison by connecting the spatial information to the frequency components. The experimental results reveal that the proposed method is efficient and produces qualitative results comparable to state-of-the-art methods.
