In this work, an attempt is made to use a new neural network training algorithm based on gravitational search (GS) and feed forward neural network (FFNN) for automatic robot navigation of wall following mobile robots. The GS strategy is used for setting the optimal weight set of the FFNN so as to increase the performance of the neural network. The algorithm is tested with three large datasets obtained from UCI machine learning repository, containing a sequence of sensor readings where sensors are arranged around the waist of the SCITOS G5 robot. The proposed method shows promising results for all the datasets.","PeriodicalId":289647,"journal":{"name":"Indo-Japan Conference on Perception and Machine Intelligence","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121014794","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}

The price of a cocoon is determined by the silk content which is determined manually by visual inspection or feeling the toughness of the cocoon shell. The above methods are subjective, non-repeatable and prone to human error. With such non-transparent conventional methods of silk estimation, the buyers and sellers are unhappy over any transaction. Our proposed non-destructive technique uses soft x-ray image analysis technique backed up by soft computing algorithm to estimate silk content. Advance image processing and analysis techniques have been applied to extract morphological features from the x-ray images of the cocoons and features are fed to GRNN to estimate the silk content. Total 594 tasar cocoons have been analyzed with the developed solution and the results have been validated with human experts. Accuracy of the system for silk content estimation has been calculated as more than 85%.","PeriodicalId":289647,"journal":{"name":"Indo-Japan Conference on Perception and Machine Intelligence","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127908231","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}

In most of the cases the face cropping is done manually and the formulae for extracting a feature point are highly complicated. In this article a facial feature extraction method is proposed where color face images are auto-cropped and control points are extracted, both using the same segmentation mechanism. The segmentation method is first used to auto crop the image and then again applied on this auto cropped image for the detection of major connected components. The feature points are detected simply using the geometrical measurement of location and size of the component without any a priory knowledge of the probabilistic distance between the feature points or using any feature point extraction formula. A T-shaped face image is formed comprising of major feature points. Recognition rate on the unprocessed face images, using PCA, is recorded. PCA is applied on the T-shaped faces and the improvement in rate of recognition is concluded to be statistically significant.","PeriodicalId":289647,"journal":{"name":"Indo-Japan Conference on Perception and Machine Intelligence","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128030553","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}

Sparse representation has already been shown in literature as a good approximation for signals for various computer vision applications. This property is leveraged to represent a dense feature like action bank in the form of sparse dictionaries. These dictionaries are learnt using on-line dictionary learning (ODL) which further facilitates incorporating new training examples into existing dictionaries for more robust representation of various categories of action as and when required. Evaluation of the proposed method on realistic action datasets like UCF50 and HMDB51 shows that considering sparse representation of a dense feature is more suitable for classification than the feature itself.","PeriodicalId":289647,"journal":{"name":"Indo-Japan Conference on Perception and Machine Intelligence","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124930847","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}

The same objects of different size and orientation could also be tagged in the same RDCR when orientation and scale maps are used as pointers. Hence after object collection and flattening in document image processing system, the compression ratio would be improved by employing OS-RDC (Orientation and Scale Mapped Reusable Document Component) which in turn would improve the performance of the system (as printing system). But especially for the scaled down and non-orthogonally rotated objects, jagging effect creates significant imaging artifacts in terms of image quality degradation. The current paper addresses to improve the perceptual image quality through OS-RDC and perception based anti-aliasing (PAA) filter. The combination of OS-RDC (used to achieve better speed) and PAA (used to improve the quality of the geometric transformed images) ensures both compression ratio and IQ (Image Quality) which are generally antagonistic in nature.","PeriodicalId":289647,"journal":{"name":"Indo-Japan Conference on Perception and Machine Intelligence","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123170259","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}

Performance is analyzed with Mel frequency cepstral coefficients (MFCC) and Gammatone frequency cepstral coefficients (GFCC). The Gaussian mixture model approach is used for speaker modeling. Two databases, namely, Marathi and Hindi databases were used for the experimentation. It has been observed that the cubic-root based features outperform the log based features under noisy conditions with SNR < 20 dB.","PeriodicalId":289647,"journal":{"name":"Indo-Japan Conference on Perception and Machine Intelligence","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114919519","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}

Most CBIR systems rely on the global content of the image but the desired content in an image is often localized, demanding the need for an object-centric CBIR. We propose a cognitive inspired framework WOR (What Object to Retrieve), to solve the problem of an object-centric CBIR. The key contributions in the proposed approach are: (i) Automatic creation of class dendogram in kernel feature space, for an efficient object recognition task; (ii) Integration of information from \"What\" and \"Where\" channels in an iterative feedback mechanism, to filter erroneous contents in the outputs of individual modules. Finally, our system extracts HOG feature descriptor from the output of Where channel, for detecting similarity and rank-order the retrieved samples.
