The main components of our system consists of a SCARA, a stereo camera, a conveyor belt, motors controlled by Arduino boards, and a computing station. In addition to the hardware composition, a set of specified markers, namely ArUco, is used to determine the target position where the puzzle cubes should be placed. The main procedure of our proposed algorithm for realizing a 3D puzzle game includes the following stages: initializing robotic system, localizing the target positions through ArUco markers, detecting any puzzle cube in an image capture, extracting the upper surface of the detected cube, defining the drawing point and pose, and picking and placing the puzzle. After all the cubes of puzzle are placed on their target positions, two single-axis slider are used to put the cubes closely. The main achievements of this study is making the robotic have vision and then combining deep learning and image processing.","PeriodicalId":359822,"journal":{"name":"2021 International Symposium on Intelligent Signal Processing and Communication Systems (ISPACS)","volume":"129 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130235411","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper presents a non-iterative image sharpening algorithm based on the frequency-domain analysis. This algorithm greatly improves the noise sensitive issue in classical unsharp masking technique. Furthermore, the non-iterative property is conducive to the hardware acceleration design. Considering the design of hardware acceleration, we focus on the three parts with the highest computation load of the algorithm, including FFT/IFFT unit, Wiener deconvolution process, and the least square method. Through the hardware acceleration, this algorithm is more suitable for applying to the real-time image recognition system. The experiment results show that this algorithm enhances the feature and contrast of image with effective noise reduction and achieves a throughput 30fps.","PeriodicalId":359822,"journal":{"name":"2021 International Symposium on Intelligent Signal Processing and Communication Systems (ISPACS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129206967","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the hole-filling method is still the main challenge in the DIBR engine because of the occlusions of foreground objects. While looking into the video sequences, the occluded parts in a frame may be revealed in the past or future frames. The temporal information could be the useful cues to recover the occlusions of the current frame. In this paper, we design an encoder-decoder neural model with a bounded region attention module to effectively fill the holes.

First, a novel equivalent circuit of the π-network is proposed. The equivalent circuit is composed of two spur lines connected back-to-back, and the impedances of the spur lines are half of those of the line elements in the π-network. The proposed equivalent circuit is then applied to replace the high impedance stubs in the conventional optimum distributed HPF design. An improved design of line elements with reasonable impedances can thus be developed for the practical implementation of optimum distributed highpass filters. A test example with the pole of 11 and the primary passband being 1 to 5 GHz is designed and implemented. Comparisons between the measured and theoretical simulated results are performed to verify the proposed design.","PeriodicalId":359822,"journal":{"name":"2021 International Symposium on Intelligent Signal Processing and Communication Systems (ISPACS)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121307801","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Convolutional dictionary learning approximates a signal with the sum of dictionary filters and corresponding coefficients, and its cost function consists of the weighted sum of the two terms: error and regularization terms. Many studies employ the l2 and the l1 norms for the former and the latter respectively, and to increase the robustness, the l1 norm is substituted for the error term. For such optimization problems with the sum of the two convex terms, the proximal gradient method is a powerful solver; however, it is not applicable for the two l1 terms, of which gradient is not continuous at any point. This paper tries to apply the Moreau envelope for the l1 error term, and the l1 error is expressed as Huber error function, which is differentiable and Lipschitz continuous. Experimental results show that dictionaries generated with the proposed method are robuster than those with the l2 error term.","PeriodicalId":359822,"journal":{"name":"2021 International Symposium on Intelligent Signal Processing and Communication Systems (ISPACS)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132689129","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
