LR images have limitations in analyzing the phenotype or morphological characteristics of cells. Therefore, they need to be restored to high-resolution (HR) images. In this paper, we propose a zero-shot super-resolution (ZSSR) algorithm to reconstruct cell shape information. In specific, a high-frequency filtering module (HFM) is adopted to calculate the difference between HR and LR by extracting various information such as the edge and corners of cells which are high-frequency information in an image. In addition, channel attention blocks (CAB) that suppress and emphasize feature information are used for SR without being confused with similar cell shapes in an image. It also improves the generalization performance of the network by sharing the network’s parameters. As a result, PSNR is improved by 0.04dB compared to that of the previous ZSSR.

Nevertheless, the process of selecting an appropriate font can be burdensome for users as it necessitates examining all available fonts. Furthermore, users with limited font usage experience might inadvertently choose an inappropriate font. To tackle this concern, we developed a system that recommends fonts by evaluating similarity between font keyword values and emotions extracted from content through deep learning emotion analysis. Considering the disparity in criteria utilized for classifying content emotions and font keywords, the necessity arose for a mapping model to evaluate the similarity between these two sets of criteria. Accordingly we designed our mapping model constructed based on the PAD model, a framework that represents emotions along three axes on a coordinate plane. We formulated two distinct methods to assess similarity: the first converts content and font characteristics into a single PAD value, subsequently discerning the distance; The second method analyzes the Pearson correlation coefficient between the criteria for emotional classification to determine the similarity. A comparative evaluation was conducted between these two methods. The results of the evaluation affirmed that the model reflecting the correlation coefficient yielded greater efficacy. As a result, we opted for this mapping model as the approach for calculating similarity between content and font.","PeriodicalId":16316,"journal":{"name":"Journal of Korea Multimedia Society","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135979492","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, due to its uniform distribution of random selection, it sometimes occludes regions that are unrelated to the object of interest. In this paper, we propose a novel method that utilizes Gradient Weighted Class Activation Mapping (Grad-CAM) for estimating the location of the object of interest and selectively erasing the surrounding areas. By utilizing Grad-CAM, we improve random erasing for CNN models without requiring additional modules or architectural changes. We generate Grad-CAM after the intermediate epochs where CNN models have sufficient representational power for the training data. The hyperparameter that restrict the erasing to the vicinity of the object is set based on Grad-CAM, and experiments were conducted accordingly.

By this replacement, numbers of convolution operation are reduced in each layer of the backbone. This can conserve spatial information of small objects in each layer and through layers in backbone, reducing processing time. In order to evaluate the proposed method, four types of experiments were executed such as mAP comparison for our hornet dataset, another mAP comparison for the standard dataset VEDAI dedicated small objects, generalization test for RTMDet, and detection speed between the default YOLOX model and the proposed YOLOX model. As a result, the first mAP under 50% IoU condition for the hornet dataset showed 86.21% and 87.35% for the default and the proposed, respectively. The experiment, mAP test for the standard VEDAI, represented 47% and 41.7% for each model and also showed better accuracy by 5.3%. In the generalization test with RTMDet, the proposed model showed similar or higher accuracy according to IoU. In addition, in terms of speed the proposed ShuffleLayerbased backbone was faster than the default by 1.35 times due to reduced convolution parameters. Thus, experiments above verified that the proposed backbone structure for YOLOX can be effectively utilized to enhance accuracy and inference speed in real-time detection for small objects.","PeriodicalId":16316,"journal":{"name":"Journal of Korea Multimedia Society","volume":"9 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135978356","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}
