Today, the need for reliable, automated satellite image classification and browsing systems is more than ever before. Everyday there is a massive amount of remotely sensed data being collected and sent by terrestrial satellites for analysis. The use of automated tools for this analysis has become imperative due to the large volumes required to be processed on a daily basis. Our goal is to develop a prototype of Content based Image Retrieval Systems for Satellite Images, wherein the user enters query in form of a sample image and the relevant similar images based on image content are displayed as an output. The Work presents a novel approach of satellite image search and retrieval system based on colour and texture. Texture information is obtained using co-occurrence matrix of the gray scaled images. The properties like correlation and homogeneity are good parameters to measure the textural property; these are evaluated at proper offset and angle. Colour is inevitable feature that dominates the human perception most. The Hue Saturation and Value (HSV) colour space is quite similar to the way in which humans perceive colour. Making this as the foundation, the work presented here uses the combination of the HSV colour and texture feature. Results have shown that the retrieval based on combination of texture and colour based features match better with the human perception.","PeriodicalId":206392,"journal":{"name":"2011 Nirma University International Conference on Engineering","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114176890","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}

Although, lot of compression techniques are available today, any upcoming technique which is faster, memory efficient and simple surely has the greatest probability to hit the user requirements. In this paper, we have developed wavelet-based image compression algorithm using well-known Distributed Arithmetic (DA) technique. Here, to increase the compression rate, the reduction of wavelet coefficients is carried out in each level of computation with the help of RW block proposed in the paper. After computing the DWT coefficients, we apply DPCM (Differential pulse-code modulation) which is a transformation technique for increasing the compressibility of an image. Finally, the transformed coefficients are given to Huffman-encoder that is designed by merging the lowest probable symbols in such a way that, the images will get compressed. For decompression, the Huffman decoding procedure is applied in the compressed image. Furthermore, the inverse DPCM and inverse DWT is applied on the decoded data to obtain the decompressed image. For implementation, the DA-based wavelet is simulated in Active HDL tool and the final design is verified with verilog test benches.","PeriodicalId":206392,"journal":{"name":"2011 Nirma University International Conference on Engineering","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117165080","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}

Fault is an unexpected change or malfunction in the system. Fault occurring at a point in the plant may propagate further in the system. It is necessary to arrest fault propagation for economy and safety of plant. For this purpose quick detection of an unexpected deviation of process variable is necessary. This function is achieved with the help of Fault detection and diagnosis unit. Diagnostic unit also assists operators in retaining normal and safe state of the system. In this paper, I have mentioned the characteristic requirements of Fault detection and diagnosis unit and the classification of diagnostic methods. With the help of Fault detection and diagnosis, it is possible to realize continuous monitoring of plant which enables diagnosis of incipient faults and thus prevents unexpected operational upsets. Here, I have done case study for two approaches, and I have observed that use of hybrid approaches for Fault detection and diagnosis yields quick and accurate assistant to the operators compared to conventional approaches.","PeriodicalId":206392,"journal":{"name":"2011 Nirma University International Conference on Engineering","volume":"130 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125471250","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}
