blob

I am a unity developer trying my hands on opencv for the first time. My initial goal is to run the camera and detect blobs via opencv in unity3d. I am new to OpenCV and am trying to integrate it in Unity3D (on Windows 8 with Unity 4.3.2 and on a mac with Unity 4.2.1f). I followed this thread. But I am getting the following error as soon as I add a new C# script. And the moment I delete this script, the error goes (this script is Unity generated C# script). Internal compiler error. See the console log for more information. output was: Unhandled Exception: System.Reflection

I want to insert image into a table like CREATE TABLE XX_SAMPLE(ID INT ,IMAGE BLOB); So can you help out form how to insert image into the above table. Madhav Please try below code INSERT INTO xx_BLOB(ID,IMAGE) VALUES(1,LOAD_FILE('E:/Images/jack.jpg')); You should use LOAD_FILE like so: LOAD_FILE('/some/path/image.png') You can try something like this.. CREATE TABLE 'sample'.'picture' ( 'idpicture' INTEGER UNSIGNED NOT NULL AUTO_INCREMENT, 'caption' VARCHAR(45) NOT NULL, 'img' LONGBLOB NOT NULL, PRIMARY KEY('idpicture')) TYPE = InnoDB; or refer to the following links for tutorials and sample,

I am developing a chrome extension. I open an image file in canvas, I apply some changes to it, then I am trying to save it to the HTML5 filesystem api. First I get the dataURL from the canvas: var dataURL = canvas.toDataURL('image/png;base64'); Then just the data: var image64 = dataURL.replace(/data:image\/png;base64,/, ''); Then I make a Blob. var bb = new BlobBuilder(); bb.append(image64); var blob = bb.getBlob('image/png'); Then I request the file system with the following function onInitFs(); function onInitFs(fs) { fs.root.getFile('image.png', {create: true}, function(fileEntry) { //

Does amazon s3 support batch uploads? I have a job that needs to upload each night ~100K of files that can be up to 1G but is strongly skewed towards small files (90% are less than 100 bytes and 99% are less than 1000 bytes long). Does the s3 API support uploading multiple objects in a single HTTP call? All the objects must be available in S3 as individual objects. I cannot host them anywhere else (FTP, etc) or in another format (Database, EC2 local drive, etc). That is an external requirement that I cannot change. Does the s3 API support uploading multiple objects in a single HTTP call? No,

I want to download a video whose url is not simple mp4 file, but its url is blob type for eg. <video id="playerVideo" width="450px" autoplay="autoplay" height="338px" style="height:100%;width:100%;" class="mejs-rai-e" src="blob:http://www.example.com/d70a74e1-0324-4b9f-bad4-84e3036ad354"> </video> Is there any chrome extension or software which can be used to download the playing video. I just came up with a general solution, which should work on most websites. I tried this on Chrome only, but this method should work with any other browser, though, as Dev Tools are pretty much the same in them

I Just started using google app engine today, and I have fallen in love with endpoints. I made one very easily that will store an object in the datastore that just has a few string values. But I also want a small thumbnail image to go along with that datastore entity. I understand how to upload blobs from android using an HttpServlet. I was thinking of using the id of the datastore entity as the image's name in the blobstore, but I dont know how to connect the two events since I would upload the Entity to the datastore, and then the blob after that request. Does anyone know how I can get an

I am trying to display an image from a MySQL blob field. I have tried a few different things and none of them seem to work. I have tried: header("Content-type: $type"); img src = $blobData; header("Content-type: $type"); echo($blobData); Another option you might consider (assuming you are on Apache): Create an .htaccess file with a mod_rewrite for all image extensions (png, jpg, gif). Have it redirect to a php script that looks up the image requested in the DB. If it is there, it echos out the header and BLOG. If it isn't there, it returns a standard 404. This way you can have: <img src=

I have a requirement,Lets say there are 3-Users for my app. I want to add an image(Profile pic purpose) to each user so that this image can be visible to other two users who are using the same app. Just like whatsapp profile pics. So for this purpose I did the following things. Step 1 : Logged in as User1 then I added this code to upload image file. After I logged in with User1 credentials and I made Public property as YES while uploading file. NSData *imageData = UIImagePNGRepresentation([UIImage imageNamed:@"arrow.png"]); [QBRequest TUploadFile:imageData fileName:@"arrow.png" contentType:@

I have a remote database with MySQL, and I am storing photos of the users of my app on the database as a row of the database with LONGTEXT type. I transform the photos to a string with Base64. I connect to my remote database with JSON and PHP, because this, I have to use Base64, because as I know, JSON and PHP need to send strings on the parameters, and with Base64 I can transform the photo into a string. It works ok, but it's very slow. When I am loading a photo of 100 KB, it takes a lot of time, but when I am loading a photo of 5 KB it takes only two or three seconds. A friend told me to use
