[coudren]

thanks walt, it is useful, but i am lack of time to master MATLAB, my lecturer ask us to do fruit recognition assignment and due date is 2-3 days later, i need a simple source code of fruit recognition as references.

[Image Analyst]

Various types of fruits have been discussed here before. It must be a popular student project, like facial analysis, and tracking. Have you done a search? http://www.mathworks.com/matlabcentral/answers/?search_submit=answers&query=fruit&term=fruit We've talked about mangoes, apples, oranges, etc. But none has been so ambitious and comprehensive as your project: to recognize fruit, all fruit, no matter what type (color, shape, etc.) of fruit. There are probably hundreds if not thousands of fruits in the world. Do you think you could possibly narrow it down to a few well specified fruits, preferably on a blank background, so that you can do simple classification?

Where did you upload your image? I think you forgot to tell us. Try snag.gy or tinypic.com or look here: http://www.mathworks.com/matlabcentral/answers/7924-where-can-i-upload-images-and-files-for-use-on-matlab-answers

... and how should it treat tomatoes, which are botanically fruit but (in the USA) legally vegetables?

Strawberries are botanically not fruit.

[Image Analyst]

Why are strawberries not fruit? I heard that they are the only fruit with the seeds on the outside of the fruit. What about corn? High sugar content, has the seeds, not the plant itself (like lettuce or broccoli). Actually a lot of vegetables are seeds (like peas) but not sweet, so I guess the definition of fruit or vegetable could be quite complex. Do you think coudren has to decide if a pea is a fruit or not?

[Walter Roberson]

I was misremembering about strawberries; I see that

"Technically, the strawberry is an aggregate accessory fruit, meaning that the fleshy part is derived not from the plant's ovaries but from the receptacle that holds the ovaries.[3] Each apparent "seed" (achene) on the outside of the fruit is actually one of the ovaries of the flower, with a seed inside it."

I wonder what I was thinking of?

"Peapods are botanically a fruit, since they contain seeds developed from the ovary of a (pea) flower. However, peas are considered to be a vegetable in cooking."

Notice that sweetness has nothing to do with the definition.

Corn is a grain, and grain is

"botanically, a type of fruit called a caryopsis"

[Bjorn Gustavsson]

Walter, that would imply that wheat, rye and rice is fruit as well? Then where does berries fall, subgroup of fruits or completely separate?

[Walter Roberson]

"The botanical definition of a berry is a fleshy fruit produced from a single ovary."

(Which, incidentally, excludes strawberries, but includes nuts... keeping in mind that peanuts are not nuts but are technically fruits...)

Wheat, rye, and rice are all cereal grains and thus are botanically fruit.

[coudren]

thanks for the infos, and now i had narrow it down just three simple fruits, shown in here http://imageshack.us/photo/my-images/801/fruitsl.jpg.

And actually I hope can get the simple MATLAB coding to classify these 3 fruits, maybe classify it based on their color, and/or based on their shape. Thanks in advanced.

[Image Analyst]

Yes, now it's really easy.

1. Convert to hsv color space.
2. Just threshold the V channel on anything dark.
3. Get rid of small noise blobs using bwareaopen.
4. Close any holes due to specular reflection with imfill()
5. Call regionprops to get the mean Hue and area from each blob.
6. Compare that with known Hues and average areas for each type of fruit.

That's the basic process. You can look at my color segmentation by HSV demo in my file exchange for a reference.

i need the MATLAB source code for fruit recognition, with apples, ananas, kiwi, banana, pears and oranges?

[Walter Roberson]

You will need to write that code; none of us have anything that specific.

Most of that can be recognized by hue, but for distinguishing banana from apple, you might need to examine texture as well, as it is possible that the flesh will be shown, and the flesh of a white apple might not be too different in hue from the flesh of the inside of a banana, and the peel of a Golden Delicious might appear not too different from the peel of a banana.

Note: you will need to account for a variety of hues for apples. http://articles.extension.org/pages/66371/red-color-development-in-apple-fruit

Note that you cannot assume that any of the fruit are ripe: you need to account for them at all growth stages. And remember that insides and outsides might be different colors.

[NILESH HARADE]

Can anyone provide me code on classification of rice grains using image processing

[Walter Roberson]

NILESH HARADE:

Yes, classification of rice grains is not a National Security matter whose publication is forbidden, so anyone who is not under court order or exclusive contract, and happens to have code for that purpose, can provide you with the code.

I suspect, however, that no-one will provide you with code for that purpose. It is a standard sort of student project, and students are expected to write their own programs.

[Image Analyst]

These people will gladly make you a robust, professional, and thorough solution. If you jhave just some simple, practice demo image and are trying to learn image analysis, see my Image Segmentation Tutorial, and adapt it to use your rice image(s).

please provide the source code of fruit diseases detection

[Walter Roberson]

I had experienced arborists (tree specialists) out looking at my apple tree again this year. Without sending off to a laboratory, they were not able to tell whether the tree had Fire Blight or Golden Blight.

I find it very very unlikely that anyone has produced software that can detect all fruit disease just from images, while at the same time knowing which unusual images are instead caused by other factors (such as overwatering, or copper deficiency).

[DGM]

This code will detect fruit diseases among many different kinds of fruit. It is very simple and will work on any fruit you can name.

% fruits of interest
FOI = 'Passion fruit Grape Blueberry Strawberry Langsat Lychee Pulasan Jackfruit Kumquat Durian Pear Breadfruit Nectarine Coconut Orange Blueberry Dragon Fruit Mango Japanese Persimmon Chinese Bayberry Sugar Apple Raspberry Kiwi Peach Fig Pomegranate Mangosteen Pomelo Snake Fruit Melon Lime Fruit Diseases Guava Passion Fruit Asian Pear Watermelon Cherry Plum Apricot Rambutan Grapefruit Apple Lotus Fruit Orangutangerine Mango Lychee Wax Apples Starfruit Santol Mandarin Papaya Banana Avocado Lemon Longan Pineapple';

% detect the presence of fruit diseases
diseasesdetected = contains(FOI,'fruit diseases','ignorecase',true)

diseasesdetected = logical
   1

[Tokunbo]

Thank you for this great explanation. As mentioned there are many different sort of fruits, and we don't even know why some are peculiar as to having a disease. It is amazing that an algorithm can detect this with a simple code.

% detect the presence of fruit diseases.

Our eyes have great lights to identify an image. However, we cannot capture every single feature of an image, at a glance.

[Image Analyst]

@Tokunbo, @DGM was being sarcastic. There is nothing "amazing" about it. The code he gave will not detect any diseases in an image containing fruit. His code simply recognized that 'fruit diseases' was contained in the long character array he defined. And any code that could detect disease, in at least some images with some probability, will not be simple, and may need to employ hyperspectral images.

[DGM]

Yes. It was a joke to emphasize that developing any solution to a complicated problem begins by clearly defining the problem in specific terms. "Fruit diseases detection" is perhaps as vague a description as is possible without conceptually omitting either fruit, disease, or detection from the task. We're only assuming that images are involved, though it's not implied.
