{"title":"A Low Memory Requirements Execution Flow for the Non-Uniform Grid Projection Super-Resolution Algorithm","authors":"T. Szydzik, G. Callicó, A. Núñez","doi":"10.1109/ISM.2011.22","DOIUrl":"https://doi.org/10.1109/ISM.2011.22","url":null,"abstract":"In this work we present a novel execution flow for the super-resolution image restoration (SRIR) non-uniform grid projection algorithm -- the macroblock-level flow. The novel flow is compared with the reference frame-level flow. The frame-level flow is characterized by the fact that transitions from one step of the algorithm to another occur only after the current step is carried out for all macro blocks (MBs) of the frame being currently processed. The novel flow carries out complete processing of one MB before the processing of another MB starts. The memory requirements of both schemes are evaluated in detail and compared. The study on the achievable memory reduction in total memory requirements was carried out for different values of the algorithm parameters: the MB size, scale factor, search area size and number of reference frames included in the sliding frame window. The results show quantitatively that the parameter that influences storage instantiation the most and has the greatest influence on the total memory size is the number of reference frames in the sliding frame window. The conducted study shows that, for a QCIF frame format, switching from frame-to macroblock-level is feasible and fully validated functionally and that the new execution flow can lead to memory reduction by a factor of 6.8 to 40, depending on the algorithm parameters values. Memory reduction greatly facilitates hardware implementations of the algorithm and this is the main result claimed. But the reduction in memory size comes at the cost of increasing the number of memory accesses and therefore communications traffic. The increase noted in memory accesses it to be quantified in future work as well as the potential impact on power consumption. The reduction in memory size might also make it fit on chip without turning to external memory, thereby reducing power consumption. This trade off in power is yet to be quantified.","PeriodicalId":339410,"journal":{"name":"2011 IEEE International Symposium on Multimedia","volume":"6 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114122751","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 work presents a different, or even reverse, scalability approach in which a scalable codec can selectively add perceptually significant bits to a low bit rate data stream. The scalable enhancement algorithm presented here operates in the Modified Discrete Cosine Transform domain, which is popular among perceptual audio transform encoders, but its extension on other domains is straightforward. By exploiting the information of an existing low bit rate base layer, the algorithm adds perceptually significant data to the data stream according to a psycho acoustic model, and improves the audio quality at a fraction of the bit rate that would normally be required for the encoding or transmission of the whole audio piece of the same quality. Applications of this can be found in packet retransmission schemes of compressed audio networks and in remote audio enhancement.","PeriodicalId":339410,"journal":{"name":"2011 IEEE International Symposium on Multimedia","volume":"421 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115612112","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}

Furthermore, the results of objective quality modeling are used for QoE management subsequently. Therefore, the performance of QoE management process actually depends heavily on MOS. However, the rationality of MOS for QoE management is not yet technically proven in the literature. In this paper, we first prove that subject homogeneity is implicitly assumed for obtaining MOS by modeling the arithmetic averaging process from a systematic viewpoint. However, we point out that actually subjects exhibit variability in terms of quality assessment. Then we elaborate that this mismatch may results in failures if we conduct QoE management based on MOS. Finally we propose a utility-based averaging method (uMOS) which improves the performance of QoE management.","PeriodicalId":339410,"journal":{"name":"2011 IEEE International Symposium on Multimedia","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134350898","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}

Recipe format had a significant effect on the ratings given to the recipe for clarity and ease of use but not on time to complete the recipe. Analysis of cooking activity and cooks' feedback shows that cooks want (i) step-by-step recipes with ingredient quantities in the recipe step, (ii) pictures of the interim states of the recipe, (iii) videos of preparation of unfamiliar ingredients, and (iv) videos of preparation techniques with different types of utensils.","PeriodicalId":339410,"journal":{"name":"2011 IEEE International Symposium on Multimedia","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133412081","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}
