ABSTRACT
Article history:
This research was conducted to analyze the identification of eggs.
The research processes use two tools, namely thermal imaging camera and smartphone camera.
The identification process was done by using Matlab prototype tools.
The image has been acquired by means of proficiency level, then analyzed and applied several methods.
Image acquisition results of thermal imaging camera are processed using morphological dilation and do the complement in black and white (BW).
While the digital image uses the merger method of morphological dilation and opening, and it doesn't need to be complemented.
Labeling process is done, and the process of determining centroid and bounding box.
The process has been done and it can be applied for identifying of chicken eggs with the accuracy rate of 100%.
There are different methods of both images is obtained area .
which is equivalent to the difference is very small as 6 x 10 -3.

INTRODUCTION
Image processing can be done with an object that has been formed into a digital image.
In the digital image formation, it can be performed by using the image capture tools.
Image acquisition is done with thermal imaging .

Thermal imaging is a technique using infrared energy that is not visible to the human eye, emitted by the object is then converted into heat visual image .
Basically, every object above a temperature of 0 absolute emits thermal energy in the form of infrared.
So, every object can be identified by using a thermal imaging camera.
The digital image is an image taken with a smartphone camera that produces images exactly in accordance with the state of the The concept of digital image is a reflection like a mirror, which describes the real object looks like the The concept of thermal imaging explains that the objects are above a temperature of 0 .

For that enables the identification of eggs image processing by using a thermal imaging camera.
The use of this camera does not produce any radiation or negative effects on the eggs and the environment because it does not emit infrared rays or other electromagnetic waves, but absorbs infrared rays from the heat radiation emitted by the objects .

Based on the research conducted, researchers will make a difference in image processing from the use of methods, analysis, and use methods that have been done but by combining them.
In a study done by using centroid and the bounding box in determining the object and the area of chicken eggs, and used comparison preprocessing process, the methods used, and the results of image processing between the thermal imaging and digital image of the ordinary.
Image Acquisition The image is a representation .
, likeness or imitation of an object .
Image acquisition is the initial stage to get a digital image.
The purpose of image acquisition to determine the necessary data and choose the method of digital image recording.
The histogram is defined as a statistical probability distribution of each level of gray .
in the digital image .
By using this method can be performed for flattening the histogram of the image exist, so that the image can be grouped by level of the intensity values of pixels of different colors.
In the gray image (Grayscal.
8 bits, there are 256 levels of intensity values different intensity.
Morphology and Image Segmentation Morphology is an image processing technique that is based on the shape of a segment or region .
In morphology there are several operations of which are used in this study are dilation operation erosion operation and opening operation.
Image segmentation is done to separate the object with the background.
The separation process aims to simplify the process so that the object classification and counting of eggs in the image can be grouped appropriately and were counted accurately.
Segmentation has been done to the clustering process .
Operation binarisms is the segmentation process of a grayscale image to produce a binary image.
Binaries process requires a threshold value (T), the process of finding the threshold value is called thresholding the Image thresholding is a simple, yet effective, way of partitioning an image into a foreground and background .
Centroid and Bounding Box The centroid is the middle value of an object is detected, and the bounding box is a function that serves to make the appropriate box the size of the object identified .
And to assist in the process of determining the centroid and the bounding box required regionprops process.
Regionprops is a method used to measure a set of properties from every region that have been labeled in the matrix label .
