    LICODS: A CNN BASED, LIGHTWEIGHT RGB-D SEMANTIC SEGMENTATION FOR OUTDOOR SCENES
    (IJICIC Editorial Office, 2019-10) Ali Suryaperdana Agoes; Zhencheng Hu; Nobutomo Matsunaga
    One way to visually understand the scenes is through per-pixel semantic segmentation. Recently, this field has undergone heavy development following the recent success of feature learning method based on the Convolutional Neural Network (CNN). Encouraged by this observation, we present Lightweight Color Depth Semantic Segmentation (LICODS), a small numbered parameter model based on the CNN for RGB-D image semantic segmentation. Additional input modality besides the color information to enhance per-pixel class prediction accuracy is employed. On the other side, our model parameter number remains low, although dual branches exist along our model’s network. The model performs better compared with the recently published RGB-D semantic segmentation models in terms of accuracy and processing time, despite of its small parameter number.

    (Universitas Ahmad Dahlan, 2020-08) Winarno; Ali Suryaperdana Agoes; Eva Inaiyah Agustin; Deny Arifianto
    Kontes Robot Sepak Bola Indonesia (KRSBI) is an annual event for contestants to compete their design and robot engineering in the field of robot soccer. Each contestant tries to win the match by scoring a goal toward the opponent's goal. In order to score a goal, the robot needs to find the ball, locate the goal, then kick the ball toward goal. We employed an omnidirectional vision camera as a visual sensor for a robot to perceive the object’s information. We calibrated streaming images from the camera to remove the mirror distortion. Furthermore, we deployed PeleeNet as our deep learning model for object detection. We fine-tuned PeleeNet on our dataset generated from our image collection. Our experiment result showed PeleeNet had the potential for deep learning mobile platform in KRSBI as the object detection architecture. It had a perfect combination of memory efficiency, speed and accuracy.

    Artistic Characters Generated by Fractal Model Based on the Composition of Components in Grid
    (Atlantic Press - Advances in Engineering Research, 2021-01-23) Darmanto, Tedjo
    A set of artistic characters can be generated by the inverse problem method in the fractal model, which has an advantage over the traditional model in recycling the flexible art composition. The code of iterated function systems of a fractal can be generated by composing the interrelated components in the collage composition design iteratively based on the collage theorem which is ruled by a set of self-affine transformations. The fractal result is displayed by means of the partitioned-random iteration algorithm as the decoding process of multi-object of fractals as the collection of the artistic characters. The number of the partition is set based on the number of characters in a composition of the artistic characters accordingly, so the individual self-affine transformation of a character can be modified independently

    Simulating the Efficient Movement of Four Segments Robot Arm by Fractal Model
    (Atlantic Press - Advances in Engineering Research, 2021-11-23) Darmanto, Tedjo
    An interesting simulation and animation of a robot arm movement by the iterated function system fractal model can be used to plan controlling the trajectory path of the very end of a robot arm to reach the target efficiently. The efficient way can be shown by the minimum number of steps and the minimum amount of energy consumption required by the rotation and spin operations of the degree of freedom mechanism. The minimum amount of energy consumption can be obtained not only by planning to choose the path with the minimum number of steps, but also it depends on the choice of the operation mode, in the rotating or spinning mode or in the combination of the rotating and spinning modes without overhead movements

    Floods are one of the disasters that often occur in Indonesia. The problem that always arises when floods are the overflow of river water into residential areas that cannot be stopped and causes flooding. Therefore a problem arises, namely the flood detection system that makes flood warnings, which previously did not know whether the flood would overflow or not. With this system, residents will know the water level in the river, and residents will be ready before the flood comes. This system is supported by an ultrasonic sensor that will input water level data and is processed through Arduino which will output water level data through the Amazon web service which displays standby status via the website and calculates river water levels through fuzzy logic.

    Calligraphic Design in Fractal Model Based on Rectangle Collage Decomposition
    (RSF Conference Series: Business, Management and Social Sciences, 2021-12-01) Darmanto, Tedjo
    A fractal model can deliver the beauty of self-similarity feature to be used in designing artistic things such as calligraphic characters. The fractal model can deliver the power of mathematics to be used in modeling the complex things that can be handled by computer programs. This paper delivers the short-cut way to design the artistic calligraphic characters based on the modification of the existing form of the simple rectangle fractal object to construct the stroke form of the calligraphic character as the simple solution of the inverse problem. The upright collage component design of rectangle fractal object can be decomposed into many cells of collage component of a calligraphic character with equal size in the right position of the cells according to the stroke of calligraphic character designed. The short-cut way to encode the fractal object is by copy-editing the representative IFS code based on the position of the cells according to the position of each component of the stroke. The calligraphic characters in fractal form as the collection of IFS code sets are the representation of the affine coefficient functions, so they can be easily modified by means of the affine transformation function to any desired form.
