Gesture recognition using a bioinspired learning architecture that integrates visual data with somatosensory data from stretchable sensors

This paper presents the application of Gaussian blur filters and Support Vector Machine (SVM) techniques for greeting recognition among the Yoruba tribe of Nigeria. Existing efforts have considered different recognition gestures. However, tribal greeting postures or gestures recognition for the Nigerian geographical space has not been studied before. Some cultural gestures are not correctly identified by people of the same tribe, not to mention other people from different tribes, thereby posing a challenge of misinterpretation of meaning. Also, some cultural gestures are unknown to most people outside a tribe, which could also hinder human interaction; hence there is a need to automate the recognition of Nigerian tribal greeting gestures. This work hence develops a Gaussian Blur – SVM based system capable of recognizing the Yoruba tribe greeting postures for men and women. Videos of individuals performing various greeting gestures were collected and processed into image frames. The images were resized and a Gaussian blur filter was used to remove noise from them. This research used a moment-based feature extraction algorithm to extract shape features that were passed as input to SVM. SVM is exploited and trained to perform the greeting gesture recognition task to recognize two Nigerian tribe greeting postures. To confirm the robustness of the system, 20%, 25% and 30% of the dataset acquired from the preprocessed images were used to test the system. A recognition rate of 94% could be achieved when SVM is used, as shown by the result which invariably proves that the proposed method is efficient.

Semiotic Approach

ABSTRAKPenelitian ini membahas tubuh dan seksualitas perempuan dalam iklan ResikV dan Sumber Ayu. Iklan yang diteliti adalah Resik V Khasiat Manjakani versi InnekeKhoeserawati dan Sumber Ayu Sabun Daun Sirih versi Dian Nitami. Penelitian inimenggunakan pendekatan semiotika, dengan mengkaji tanda-tanda pada iklan di dalamdata tekstual maupun visual baik secara denotatif dan konotatif. Tujuan penelitian iniadalah untuk memperoleh gambaran mengenai tubuh dan seksualitas perempuan didalam iklan. Penelitian ini menunjukkan bahwa genitalia perempuan ditempatkan sebagairepresentasi keseluruhan diri perempuan. Penggambaran seksualitas perempuan didalam iklan menunjukkan beberapa kecenderungan yaitu perempuan sebagai penjagakeharmonisan rumah tangga, sebagai penjamin terpenuhinya hasrat seksual laki-laki,serta adanya tuntutan bagi perempuan untuk mempertahankan kemudaan tubuh danseksualitasnya. Kedua iklan juga mengerucutkan perempuan pada fungsinya sebagaiistri yang mengurusi suami serta pada fungsi domestik sebagai pengurus rumah tangga.Kata Kunci: iklan, perempuan, seksualitas, semiotika, tubuhABSTRACTThis research discusses body and sexuality of woman in Resik V and Sumber Ayuadvertising. Spesifically, the ads discussed here are Resik V Khasiat Manjakani in InnekeKoesherawati’s version and Sumber Ayu Sabun Daun Sirih in Dian Nitami’s version. This researchapplies semiotic approach in which the signs in textual and visual data are examined in thedennotatif and connotatif order. The aim of this research is that to find out how women’s bodyand sexuality are represented in Resik V and Sumber Ayu. This research shows that woman’sgenital organ is positioned as the representation of the whole woman’s Self. The description ofwomen’s sexuality in both advertisings points out several tendencies which are as follows. Firstly,woman is positioned as a person who is responsible to keep the marriage in harmony. Secondly,woman is pictured as person who guarrantees the fulfilment of man’s sexual desire. Thirdly, theads indicate a demand on woman to keep their body and sexuality young and fresh. It can also besaid that both Resik V and Sumber Ayu narrow the function of woman as wife who is in chargein serving their husband well and focus to highlight the domestic function of woman.Keywords: advertising, body, semiotics, sexuality, woman
